We will send the material to you by e-mail

The DSP board, oriented towards construction and repair work, is rapidly conquering the consumer market, the dimensions and prices of which allow it to be used for various purposes. We invite you to evaluate the advantages of a relatively new building material and study it specifications, size range. You will learn about the basic rules for using DSP when installing floors, as formwork or as a basic element in production. The features of installation using DSP will be discussed, as well as a brief overview of the main manufacturers of this material will be offered.

Facades finished with DSP take on a stylish, modern look

DSP is a cement-bonded particle board. In English it sounds like “cement bonded particle board”. Refers to a variety of sheet composite material intended for use in the construction industry.

Characteristics of CBPB boards: sheet dimensions and price, thickness, weight

Thanks to the variety of technical indicators that meet modern requirements, cement-bonded particle boards seriously compete with the common flat slate and other sheet materials.

DSP board: technical characteristics, application

The main document that regulates the characteristics and use of CBPB boards is GOST 26816-2016. According to its provisions, two brands are distinguished - TsSP-1 and TsSP-2. They have some differences in the values ​​of technical parameters.

Table 1. Technical characteristics of the DSP

The scope of application of cement bonded particle boards is quite extensive and includes several areas:

Weight of CBPB boards

Weight is most often assessed building materials, if you have to build a low-rise building on your own. This indicator is directly proportional to the thickness and dimensions of the material.

If we consider a cement particle board with a length of 2700 mm and a width of 1250 mm, then the weight indicators depending on the thickness will have the following values.

With a length of 3200 mm and a width of 1250 mm, the weights will be as follows.

Note! Analyzing the indicators, it can be noted that with a thickness of 36 mm, the slabs become 4.5 times heavier than their eight-millimeter counterparts. Even 10 mm DSP has a fairly impressive weight, so it will be difficult for one person to work with such material.

Advantages and disadvantages of cement bonded particle boards

The popularity of DSP is based on a wide list of advantages of this material compared to analogues:

• Fire safety. Finishing made of cement-bonded particle boards does not support combustion. If a strong fire occurs nearby, they do not emit dangerous toxic elements.
• Multifunctionality. Possibility of using the material in different roles: partitions, finishing, creating a rough foundation.
• Biostability. Cement particle boards are not colonized by fungi. They are resistant to rodents and various bugs.
• Frost resistance. This characteristic becomes especially important when using the material in regions with severe winters.
• Reliability. Even in conditions of frequent temperature fluctuations of the slab long time are not subject to deformation.
• Noise insulation. The structure of the slabs allows you to protect living spaces from external sound influences.
• Moisture resistance. Even when used for finishing external facades, the material withstands atmospheric conditions well.
• Quick installation. If a private house is being built, its finishing using DSP is carried out at a rapid pace, due to the large area of ​​​​the sheets.

Among the disadvantages is the high weight of the material, which makes it difficult to use on upper floors without special equipment. Another inconvenient factor is the abundant formation of dust during the sawing process of slabs.

What and how are CBPB boards made from?

The composition of cement bonded particle boards includes the following components:

• Portland cement −65%;
• wood shavings −24%;
• water −8.5%;
• additional impurities - 2.5%.

As a supplement, aluminum sulfate and liquid glass are used. It is necessary to pay attention to the product passport, which reflects these indicators. Also included is a certificate of certification and a quality passport.

The technological process consists of several stages:

• The chip component is mixed with hydration additives.
• Water and cement fraction are added.
• A slab is forming required sizes under pressure.
• It should be heated to 90 degrees and hardened under such conditions for eight hours.

The slabs are then aged to achieve their final hardness levels. natural conditions in two weeks. The last stage is grinding, if provided for in the technological map.

Slab manufacturers have special equipment, conveyor lines, comply with GOST standards, carry out the necessary quality control.

Main sheet sizes, prices and where to buy cement bonded particle board

GOST 26816-2016 regulates two standards for the length of CBPB: 3200 and 3600 mm. And also two width options: 1200 and 1250 mm. Among the assortment different manufacturers the most popular products are 2700 cm long with standard width. Thickness values ​​starting from 8 mm are graded in 2 mm increments. GOST reflects the possibility, if necessary, to order the manufacturer to produce slabs with other sizes.

The price of building materials also depends on the main dimensions. Below is an overview of the cost of the most popular types of cement bonded particle boards.

With a length of 2700 cm and a width of 1250 cm, prices vary within the following limits depending on the thickness.

The price for dimensions 3200x1250 mm is the following average values.

Price for dimensions 3600x1200 mm.

Based on average prices, you can calculate how much the modern material needed to carry out the planned work will cost. For example, the price of a 16 mm DSP board with a length of 3600 mm is 1500 rubles. To cover the facade, 35 slabs will be required. Therefore, you will have to spend 52,500 rubles on the purchase.

You can purchase cement bonded particle board in stores specializing in the sale of building and finishing materials. Here you can get the necessary advice on choosing the right variety.

You can find many offers in online stores both from manufacturers and from representatives of companies producing this modern and popular material.

Handling rules - how to cut CBPB

Cement particle boards, which are superior in hardness, cause virtually no difficulties during processing. They drill and mill well. For example, screw drills are used to drill a hole and the work is done at high speed.

If it is necessary to cut CBPB, then different tools are used at home. Be sure to wear safety glasses and a mask over your mouth and nose, since a large number of dust.

Expert's point of view

Dmitry Kholodok

Technical director of the repair and construction company "ILASSTROY"

“You can use an electric jigsaw, but you should choose special files designed for cement. They are equipped with carbide tips.”

To reduce the amount of dust formation, it is recommended to irrigate the cutting area with water from time to time. You can remove dust immediately using a vacuum cleaner, which should be held by an assistant.For slabs thicker than 12 cm, it is advisable to use an electric disk tool.

Advice! Select discs that are designed for working on concrete, stone or brick. They are diamond coated. Preference is given to a circular saw, since when working with it, less dust is generated than from an angle grinder.

Scope of application of DSP in construction and repair

Considering the characteristics of DSP, its scope of application is quite extensive. When using, recommendations for selecting material thickness are taken into account.

DSP façade finishing

Facades finished with cement-bonded particle boards acquire a presentable appearance; the brick-look CSP coating looks especially attractive.

This building material does not require additional coating, reliably protecting the building from external influences. You can purchase cladding with the texture of stone, marble and other types of crumbs.

If the goal is insulation, then a material with a thickness of 8–16 mm is used, under which the insulation is first laid. Then the sheathing is formed and the facing slabs are fixed. A ventilation gap is provided.

Application of DSP boards for flooring

DSP is becoming a popular material when laying floors. If you plan to directly lay the DSP on the floor along the joists, the thickness of the material is selected in the range from 20 to 26 mm. This provides good strength with an average lag pitch of 0.6 meters.

The result is a smooth rough base, ready for finishing. Self-tapping screws are used as fasteners.

Often, 12mm DSPs are used to level a floor structure whose structure is multilayer. In such a situation, logs, waterproofing, and plank covering are laid on the subfloor. The next layer is DSP, providing not only a flat floor surface, but also sound insulation.

If you use DSP with a decorative front layer, you can immediately get a clean floor without the need to lay other materials on top. This material is also used for installation. When constructing utility and storage buildings, laying slabs with a thickness of 24-26 mm is allowed directly on leveled bulk soil.

Production of SIP panels from DSP

An improved version of the new generation of building materials are SIP panels, the basis of the design is DSP.In the production process, a sandwich is formed, for which insulation is placed between two cement-bonded particle boards, fixed under high pressure using glue.

The resulting structure is highly durable and does not require additional operations to insulate the building after installation. When using quality types heat-insulating layers SIP panels are environmentally safe and resistant to fire.

Article

Cement particle boards (CPB) are a whole class of building materials with different characteristics.

They are used for various purposes, using the advantages that they have over traditional finishing and structural materials.

The scope of application directly depends on the type and density of the DSP, so we recommend that you read the articles:

1. Production of CBPB: step-by-step guide, regulatory documents and necessary equipment.
2. Fibrolite.

In these articles, we talked about the different types of cement bonded particle boards, as well as the differences in the original components and their proportions.

Even with the same density, the basic parameters of TsSP-1 and TsSP-2 boards are very different from fiberboard boards of any type. This associated with different amounts of cement, as well as different requirements for wood filler.

• what can DSP be used for?
• how to choose materials for a particular application;
• what are the advantages of properly selected slabs over other materials;
• how to attach panels to walls or to a wooden floor, how to saw them, glue them together, prime them, and how to process DSP differently;
• how to lay tiles on DSP;
• how to paint the facade of a building on which DSPs are installed, and how to protect this material from moisture and other negative factors.

Here are the main areas in which cement bonded particle boards can be used:

• structural elements (walls and partitions);
• insulation of walls, floors and ceilings;
• soundproofing;
• external and internal finishing;
• permanent insulating formwork;
• creation of greenhouses, beds and other areas.

Structural elements

From the DSP you can create various partitions dividing the room into separate zones or parts.

Due to their high rigidity and strength, slabs in this area are not inferior to such materials as:

• wooden plank;
• plywood;

However for creating partitions and walls according to technology without a supporting frame, only cement-bonded particle boards with a density of over 1000 kg/m 3 are suitable, and best results show TsSP-1 and TsSP-2.

Fiberboard boards with equal density turn out to be less durable because they contain less cement.

However, full walls big size it will not be possible to make one from this material due to the size of the sheet, because the maximum width does not exceed 125 cm, so the sheets will have to be stacked on top of each other.

Therefore, to create full walls and large partitions necessary load-bearing frame , but the same limitation applies to others structural elements, comparable in size.

The exception is cases when it is possible to place cement-bonded particle boards vertically and securely fasten them at the top and bottom.

Moreover, such a wall will only fulfill decorative function and is not designed for any kind of force.

With a slab thickness of 30–50 mm, a door or arched opening can be embedded into a wall of this design, the main thing is that its width does not exceed 1.5 times the width of the DSP slab.

If the width of the area that needs to be partitioned does not exceed the width of one sheet, and there is no force impact on it, then you can use a material with a thickness of 10–15 mm (when using fiberboard boards, the thickness must be increased to 20 mm).

At the same time, compared to other structural materials of the same thickness, CBPB will provide much higher level of noise and heat insulation.

Insulation for house facades and walls, floors, ceilings

To insulate a house, you can either use DSP inside or cover the façade of the house with this material. It is better to use cement-bonded particle boards of any type as insulation. with a density of 250–350 kg/m 3, however, fiberboard is more effective due to less cement.

Despite the low density, the strength of sheets of any thickness is sufficient to be attached to the wall either with glue or with anchor nails.

DSP is somewhat less efficient compared to foam plastic (thermal conductivity of boards is 0.06, foam plastic is 0.04), but they freely allow water vapor to pass through, due to which the premises always maintain a favorable dry climate.

DSPs are only slightly inferior mineral wool(the thermal conductivity of slabs with a density of 300 kg/m 3 is 0.06, and that of wool is 0.05), but an increase in humidity does not affect their characteristics.

In addition, their can be installed on flat surfaces without a special frame, and to protect against precipitation, a thin layer of plaster or even waterproof, vapor-permeable paint is sufficient.

Despite the fact that polyurethane foam is easier to apply, working with it requires expensive, highly specialized equipment, the price of which starts from 40 thousand rubles.

Besides, polyurethane foam does not allow water vapor to pass through at all, therefore, after insulating it in houses with a not very good ventilation system, the climate becomes damper, and mold and rot also appear.

The costs for working with any type of DSP are much lower, and the equipment can be used for many other jobs.

When insulating ceilings, cement particle boards are hemmed from below using glue and anchor nails or self-tapping screws. However, this method of application can only be used in houses and apartments with durable floors and reliable ceiling lining.

Best suited for these jobs fiberboard boards with a density of 250–350 kg/m3, because they contain more wood than products of the TsSP-1 and TsSP-2 brands. Maximum thickness slabs depends on the strength of the floor and the ability to securely attach the insulation to it.

Using this material, it is possible to completely construct and install the roof of a house, as well as build the entire house as a whole.

To insulate the floor, the slabs are laid either on a concrete screed or on a rough flooring.

If the base is not too level, then to level the floor it is advisable to pour a layer of solution, this will allow the maximum potential of the DSP to be realized.

After all, all materials of this type, manufactured according to GOST or international standards, are the same in thickness and have a smooth surface.

Thanks to this, it will be possible to lay parquet, laminate or linoleum on them without additional layer. The optimal density of material such as TsSP-1 and TsSP-2 is 500 kg/m 3 , the optimal density of fiberboard is 800–900 kg/m 3 .

Quite often they use the technique of laying CBPB on the floor along wooden logs, and the thickness and density of the slabs required to ensure the strength of the floor in the house varies in this case will depend on the distance between the installed logs.

Laying DSP on the floor, including wood, under tiles is ideal option in the bathrooms.

To begin the installation of tiles, it is enough to use cement-bonded particle boards Apply a couple of coats of regular primer to improve adhesion.

If it is necessary to insulate the base of a heated floor, including if it is mounted under tiles, then the density of the sheets depends on its design. If the heating element is immured in the screed, then it is advisable to use slabs density 300 kg/m 3.

If the heating element is laid between wooden or aluminum supports, then it is advisable to use a material of the same density as for a regular floor.

When insulating the floor with cement-bonded particle boards, it is necessary to ensure reliable waterproofing, since water that gets under the front covering will be absorbed into the insulation, but will have difficulty coming back due to poor air exchange.

Long exposure to high humidity will reduce strength cement-bonded floor and will lead to the appearance of mold and rot in the chips, which will negatively affect its thermal insulation properties.

Soundproofing

Residents of Soviet-built multi-storey buildings suffer greatly from poor sound insulation, because in the apartments you can hear everything that happens at a distance of several floors. Often even residents of private houses are looking for ways to improve sound insulation to reduce the level of noise coming into the rooms from the street.

Low-density cement-bonded particle boards, although inferior to many modern materials with the same thickness, but due to their minimal cost and ease of installation on walls, floors, etc., they are very popular.

The most effective in this area are fiberboard boards of the GB-1 standard and their magnesite analogues.

The maximum soundproofing effect is achieved not only by increasing the proportion wood waste, but also located along the slab. However, TsSP-1 and TsSP-2 slabs with a density of 250–350 kg/m 3 are also good for noise reduction.

To increase the sound insulation effect between the slabs and the wall/ceiling, you need lay a layer of felt 2–6 mm thick.

Having sheathed the ceiling with slabs 2–3 cm thick and laid felt, you lower the level entering the apartment noise tenfold. In this case, it is important to join the slabs tightly so that there are no gaps between them, otherwise the effectiveness of such sound insulation will sharply decrease.

For exterior work and interior decoration

The purpose of exterior and interior decoration is to hide wall defects and make the exterior or interior more attractive. All types of DSP are well suited for rough finishing, over which a fine finish can be applied.

Cement particle boards of any type have high strength, but a material with a density of less than 700 kg/m 3 cannot be used for exterior finishing, and less than 1000 kg/m 3 for interior finishing.

As the density increases, the rigidity and strength of the product increase, which is especially important in regions with frequent strong winds.

Interior finishing material must be able to withstand the screw being screwed in with a small load, therefore, the use of cement bonded particle boards for interior decoration is not high density unjustified.

In most cases this finishing material must be attached to a special frame that compensates for the unevenness of the walls. In addition, the frame ensures air movement under the finish, due to which condensation on the wall evaporates faster and does not lead to an increase in humidity of the wall or finish.

If the frame is made correctly, then after installing the slabs they form a flat surface, so it is enough to fill the seams between them with mortar or putty, after which walls are ready for finishing.

The most effective finishing materials are TsSP-1 type slabs with a polished surface.

They are attached to the frame using appropriate self-tapping screws - for wooden blocks you need self-tapping screws with wood carvings, for aluminum or steel profiles Self-tapping screws with metal threads are required.

As an interior decoration, sheets based on chip concrete have a significant advantage - they do not emit toxic substances, which cannot be said about:

• plywood;
• plastic;

The only materials that can significantly compete in terms of environmental safety are natural boards and real MDF, made without the use of glue.

However, they have serious disadvantages compared to cement bonded particle boards:

• less rigidity, forcing an increase in the thickness of the finish;
• much higher flammability;
• higher price.

Therefore, as an environmentally friendly material for interior decoration, all types of DSP have no equal in terms of the totality of all parameters.

• do not emit toxic substances in normal conditions;
• able to withstand high temperatures for a long time before the process of pyrolysis in sawdust begins;
• do not support combustion and go out after the source of open fire disappears;
• even during a fire they do not emit toxic substances, with the exception of carbon monoxide and carbon dioxide, but these substances are released during combustion by any organic matter;
• albeit insignificantly, they perform the functions of insulation and sound insulation.

For the exterior decoration of the facade of a house, the most popular are cement-bonded particle boards and panels of the TsSP-1 type with a density of 1100–1400 kg/m3 and a thickness of 1 cm.

With the correct selection of the distance between the frame slats, such exterior decoration of the house easily withstands wind speeds of 40–50 m/s. An example of finishing the facade of a house is shown in the photo below.

Fiber cement boards of the same density must be chosen with a greater thickness due to the lower cement content, so most often for external work a material with a thickness of 15–20 mm is used. He has the same resistance to precipitation and wind load.

Between the wall of the house and the finishing, you can install insulation made of shavings and cement, which has excellent reviews, or other material.

Due to the fact that during rain, water quickly drains from the surface of the façade cladding panels, the slabs do not have time to absorb much water, so even in the event of a sharp drop in temperature after prolonged rain, they will not suffer severe damage.

Treatment with hydrophobic paints for exterior use and preparations that do not affect vapor permeability, further reduces the material’s ability to absorb water.

Thanks to this, any type of DSP as an exterior finish is in no way inferior to traditional plaster.

Thanks to these properties of the material, the ease of its finishing (painting), as well as numerous reviews from residents, cladding the facade of a house with DSP can be safely called the best option for climatic conditions many regions of Russia.

In addition, manufacturers also produce facade panels that do not require additional finishing for cladding houses, including frame wooden ones, performing at the same time a decorative function.

For example, facade and plinth panels under the stone, under the brick, under the crumbs and others.

Such facade panels carry out finishing of the foundation of the house, the basement, including screw piles.

Do-it-yourself permanent insulating formwork

The construction of houses from monolithic concrete is gaining increasing popularity because it allows you to build walls much faster than any other methods.

Permanent formwork not only creates a form for concrete, but performs a warming function, due to which, after the concrete has gained full strength, the wall is completely ready for finishing and does not require additional insulation.

The only one competitor cement bonded particle boards in this application – permanent formwork made of expanded polystyrene(PPS), however, it completely blocks the vapor permeability of the walls, which is why problems begin in houses with a not very good ventilation system.

Unlike polystyrene formwork, which is supplied in the form of ready-made small blocks, formwork made from cement bonded particle boards need to make it yourself.

As in the case of EPS formwork, DSP formwork must be carefully reinforced with numerous bridges to avoid squeezing out the slab with concrete.

This is especially true when using heavy concrete, but it will not be superfluous when pouring foam concrete.

In addition, it is necessary strengthen formwork over the entire area using various pegs and spacers, which will protect it from shifting during filling with concrete and its compaction.

It is advisable to use sheets for the manufacture of formwork density over 1000 kg/m 3, and the thickness of the sheet directly depends on the desired thermal insulation effect.

Therefore, sometimes they make double formwork - install inner sheet DSP with a density of 1200–1400 kg/m3 and a thickness of 10 mm, and a sheet of fiberboard with a thickness of 50–100 mm and a density of 300 kg/m3 is placed close to it.

When using foam concrete, such a design will ensure such a low level of heat loss that even in conditions northern regions no additional insulation required.

However, permanent formwork made from DSP also has minus- her cannot be used below ground level, since under the influence of groundwater the wood will eventually lose its thermal insulation properties, and the cement stone will collapse.

But as formwork interior walls DSP has no equal, because after the concrete has hardened, the wall surface is ready for finishing, and it also has, albeit small, a heat and sound insulation effect.

Greenhouses and beds

Cement particle boards, even when buried in the ground, capable of standing like this before destruction for several decades, due to which they are often used to create do-it-yourself or fencing greenhouses and beds. After all, without boards special processing will rot into dust in 3–5 years, and the DSP will last 20–40 years without requiring replacement.

Most often, plates are used for this density over 1000 kg/m 3 and thickness 8–12 mm.

Another advantage of cement-bonded particle boards is that greenhouses and garden bed fencing made from CSP look very neat thanks to the smooth walls.

The same effect is created by the carriage board, but its service life and high price do not allow it to compete with CBPB.

Chipboard, plywood and other similar materials also cannot compete with these boards, because even those that are called waterproof quickly collapse once they are in the ground.

If the wall height is small, you can do without a frame by connecting the slabs together using plastic corners, if the height or length of the structure requires the use of several slabs, you cannot do without a frame.

As a frame, you can use either boards impregnated with hydrophobic compounds (such compounds spoil the soil) or designs based polypropylene pipes large diameter.

If the pipe diameter exceeds 30 mm, and the frame design is well thought out, then the greenhouse or bed turns out to be quite strong.

You can reduce the diameter of the pipes by inserting pieces of metal or fiberglass reinforcement into them, but in this case you will have to attach the DSP use short jumpers.

Due to the fact that the cost of a sheet rarely falls below 500 rubles, many people prefer used cement particle boards that were dismantled during repairs.

Such CBPBs do not have a very good appearance, and their strength is much less than new ones, but they are quite in demand for fencing beds and creating greenhouses, as can be concluded from numerous reviews from gardeners. Moreover you can buy them very cheap or get it for free.

In addition to the listed areas of application, DSP, due to its properties and affordable cost, is also used to build bathhouses with your own hands, including floors in it, lining garages, sheds, building fences, mounted on roofs, etc.

Processing and installation of sheets

Cement particle board, in its physical characteristics, is very different from most finishing materials, so its processing occurs according to a special algorithm and using special tool.

Violation of the work algorithm and the use of inappropriate tools are often leads to material damage and the need to replace it, and given the considerable price of any type of DSP, including, for example, sheets for floors or slabs for facades such as brick or tile, this attitude turns out to be extremely unprofitable.

What to cut with?

To cut this material you will need hand circular saw, equipped with a disk with carbide (pobedite) nozzles or diamond-coated teeth.

If there is no such disk, you can use a suitable size abrasive cutting disc for stone with a bore diameter of 32 mm.

If you need to cut a sheet or cut a hole in it rectangular shape, then place it on a flat table so that the cutting line is 2–4 cm away from the edge.

Required for cutting use a respirator and safety glasses, and also do not forget to fasten the sleeves of your clothes. Place the saw blade on the sheet so that the blade is 3–5 mm away from it.

Turn on the saw, then move it smoothly forward so that the blade follows the cutting line. The speed of the saw depends on the density and thickness of the sheet, so rely on your own feelings.

At normal speed movement, the sound of the saw engine almost does not change, and forward movement resistance is minimal.

If the sound changes (the speed drops) or the resistance to movement increases, then you are moving the saw forward too quickly, which is why the blade does not have time to cut the cement stone properly. To reduce the amount of dust and improve the quality of the cut, you can pour water on the sheet along the cutting line.

If the dimensions of the cut piece exceed 20 cm on any side for thin slabs and 10 cm for thick ones, then an assistant must support the cut piece so that it does not break off.

Care must be taken so that your fingers do not get in the path of the saw.

To cut a round or oval hole, you must first draw it on a sheet of paper, then write a rectangle into it. Moreover, the distance from the drawing to the edge of the rectangle should never be less than 3 cm.

If you know how to cut with a circular saw not from the edge of the sheet, then cut out a rectangle with it, if not, then use a grinder(angle grinder, angle grinder) with abrasive disc for stone.

Having cut out a rectangle, mark parallel strips on the remaining parts of the slab inside the pattern in increments of 1–1.5 cm, running from the edges of the rectangle to the edge of the pattern. Cut these strips 3–5 mm short of the edge of the pattern.

Then cut through sheet according to the drawing using a jigsaw with a diamond file, designed for cutting glass or ceramics.

This sequence of actions increases the time required to cut a hole, but greatly reduces the chances that you will ruin the material. After all, when cutting a hole with a diameter of over 40 cm, there is a possibility that the cut piece will break off, and the fracture line will affect the remaining sheet.

If you are a skilled, experienced finisher and therefore know how to work well with materials such as:

• ceramic tile;
• smooth slate,

then you can cut or saw oriented strand board than you are used to, because the behavior of these materials when cutting is very similar to the behavior of OSB of any type.

• self-tapping screws;
• anchor screws (dowel-nails);
• rivets.

Self-tapping screws are well suited for fastening DSP to a wooden or metal base.

If you only have ordinary hardened self-tapping screws, then you need to drill a hole in the slab for them, and also countersink the space for the head. Without this, the cap will protrude above the surface of the slab, which will create great difficulties during finishing.

You can screw in reinforced screws without drilling, the caps of which are equipped with knives and cut a hole for themselves. The diameter of the hole for a regular self-tapping screw is equal to 1.2 times the diameter of the screw itself, and the diameter and depth of the hole for the head are 1.5 times larger than the size of the head.

It is not advisable to use ordinary screws for fixation, because they do not have the required strength, so with their help you will not be able to properly tighten the slab to the base.

After installing the screws, the holes for the caps must be sealed with putty, and after drying, treat it with sandpaper.

Anchor screws are used in cases where the panel needs to attach to concrete or wooden wall . To do this, place the plate in place and drill a hole for the plastic dowel. For fastening low-density slabs (300–500 kg/m3) It is advisable to use dowels with large heads for more effective fixation.

Such caps distribute the pressure created by the dowel-nail over a large area, so that the cement stone does not receive damage. In high-density slabs (over 700 kg/m3), everything is done in the same way as when fixing with self-tapping screws.

Rivets use for quick fixation to steel or aluminum profiles, where for some reason it is impossible to use self-tapping screws.

To do this, the sheet is put in place, then a hole is drilled, the diameter of which is 1.2 times the diameter of the rivet.

After this it is necessary Using a special cutter, select a mounting hole under the rivet head.

If this is not done, the cap will protrude above the surface of the slab. It is also impossible to use a regular drill instead of a cutter, because The cutter makes a hole with a flat bottom, to which the head will be pressed tightly, and the drill makes a conical hole.

The cap will not be able to press evenly against such a hole, so over time the fastening will weaken and the plate will begin to dangle. If there is no cutter, it is better to leave the rivet heads outside, they can be closed thin layer plaster. This will be better than using a drill.

Finishing

The front surface of any cement bonded particle board is very smooth, so after covering the walls of a house with this material, it is enough to carry out only the final finishing.

To do this, first carefully putty the seams, trying not to stain the slabs too much. Then, when the putty dries, joints and seams clean with sandpaper.

After this, wallpaper is pasted, painted or any other finishing option is performed.

To apply wallpaper, use glue that is suitable for the selected type of wallpaper and is suitable for brick or concrete surfaces. For laying ceramic tiles, use only cement based adhesive, because it has the same temperature expansion as the DSP, so it will not crack due to temperature changes.

During the work, the glue is dosed with a special notched spatula.

If you decide to paint the walls, then use any vapor permeable paints and varnishes , suitable for painting brick or concrete surfaces.

Video on the topic

Below is a video filmed by one of the Russian construction companies about the advantages of constructing residential buildings from cement-bonded panels using the example of one of these buildings. As you can see, the facade of a house made of this material is ready for painting immediately after its construction:

In contact with

For comparison with other materials, we suggest using characteristics such as:

• fire safety;
• ease of installation;
• resistance to mold and disease;
• builder reviews;
• reviews from residents and home owners.

Fire safety and flammability class

In this parameter, DSPs are superior not only to polymer insulation and PVC, but even to wood concrete. DSP is assigned a flammability class - G1, that is, they are difficult to burn. Thanks to the large proportion of cement, each of the chips is surrounded cement stone, That's why to start the pyrolysis process in wood located close to the surface exposure to temperatures of 500 degrees or more for half an hour is required.

Once the thermal effect is removed, the pyrolysis process is quickly completed, because close contact of many chips is necessary for the self-sustaining reaction to begin.

If the temperature exceeds 700 degrees, and this effect lasts for over an hour, then pyrolysis of the chips begins throughout the entire depth of the slab.

At this temperature, any building materials sharply lose strength, and concrete completely collapses. Therefore, after a fire of such magnitude, the house cannot be repaired, unless the fire was local in nature and burned only a small area of ​​the house.

Even the beginning of the pyrolysis process does not lead to the release of particularly toxic substances, because the main components of pyrolysis gas (smoke) are:

• nitrogen;
• carbon dioxide;
• carbon monoxide.

Only carbon monoxide poses a serious danger, but, firstly, very little of it is released during the pyrolysis process, and secondly, during a fire, combustion occurs in conditions of lack of oxygen, so carbon monoxide is released everywhere in huge quantities.

Therefore, DSP one of the safest in terms of fire resistance of materials and is comparable to gypsum plasterboard and fiberboards. It is much safer than finishing from:

• plywood;
• boards;
• wood concrete;
• insulating fiberboards;
• foams and plastics.

Ease of installation

Due to the high cement content of CBPB much heavier than most others finishing materials.

The weight of thin sheets is 25–45 kg, so a minimum of 2 people are required to work with them.

To work with thick sheets, 5-6 people are needed, because the weight of a sheet with a thickness of 26 mm exceeds 200 kg.

Cutting the material is also fraught with difficulties, because it is necessary to use high-speed circular saw and diamond coated disc or carbide tipped.

Therefore, in terms of ease of installation, DSP is inferior to most finishing materials. After all, its weight, with equal dimensions and thickness, exceeds the weight of any other finishing material, including LSU and wood concrete.

Resistant to mold and disease

Due to the fact that the wood in CBPB does not have direct contact with air, it is less susceptible to mold and disease.

In addition, for products manufactured in accordance with GOST requirements, the chips are pre-soaked in a solution of lime or other reagents, increasing biological stability wood.

Application of DSP for flooring

When laying DSP on the floor along the joists, it is recommended to choose a thickness of products from 24 mm to ensure sufficient strength flooring.

Fastening by joists

When working indoors, it is necessary to carry out preparatory measures - seal holes in the base, if any, fix the logs, put insulation and vapor barrier material.

Preparatory work before laying the CBPB on the floor

The plates are fixed using self-tapping screws, and the screw with a countersunk head must be immersed in the body wooden beam by 20 mm. The result is a perfectly flat subfloor with excellent performance characteristics.

Frame construction

DSPs have proven themselves to be excellent in the construction of houses frame type. There are two options - purchasing a ready-made house kit from SIP panels based on DSP or independently erecting walls between which the mineral insulation. The slabs are fixed using wooden or metal sheathing, while sewing up the frame around the perimeter, and then cutting out window and door openings. The sheathing elements are installed in 60 cm increments so that the insulating material can be firmly fixed between them. Plates are taken 10–16 mm thick and fixed with galvanized screws.

Interior finishing works

The environmental safety of cement particle boards has made it possible to use them as a full-fledged finishing material indoors for any purpose. Due to its high moisture resistance, this material has significantly replaced plasterboard, which is not recommended for use on walls in wet rooms.

Leveling the walls and floor in the bathroom

DSPs are used for effective leveling of walls and their subsequent finishing with decorative finishing materials. However, in some interiors (loft, industrial, high-tech and others), where a raw concrete texture is appropriate, DSP is used to create accent surfaces and even to cover entire rooms.

Accent wall in the bedroom at the head of the bed is made of cement panels

Fastening the plates depends on the thickness and dimensions of the sheets, and, accordingly, their weight. Heavy products are fastened along the sheathing, and light ones are secured using a special solution or mastic.

Production of SIP panels from DSP

SIP panels made of DSP are a three-layer material, where insulation made of expanded polystyrene, basalt fiber or polyurethane foam (PPU) is fixed between the sheets.

Appearance of sandwich panels

A common distinguishing feature of the material is its high fire and environmental safety. Possibility of quick construction of a private house and significant savings on facade finishing works.

Application of DSP for formwork in monolithic construction

There are a number of advantages of the device permanent formwork of this type when producing monolithic works:

1. Reduction installation work And total term construction of the object.
2. The surface is ready for finishing.
3. High profitability of the construction of the facility as a whole.
4. Guarantee of a strong and reliable structure.

Monolithic construction using permanent DSP formwork

Installation methods

DSPs can be mounted different ways depending on the purposes for which they are used. When finishing or insulating buildings, they are attached to the sheathing, made of metal profiles or wooden blocks, with self-tapping bolts or nails. The installation of permanent formwork also involves erection of the frame (considering heavy weight slabs, it, like the sheathing when finishing walls, must be strong enough). In addition, the slabs can be laid on joists (when installing the floor) or rafters (under the roofing). For interior decoration they are also can be attached to the wall with mortar or mastic.

Preparing for the installation of a DSP coating

Before starting work on arranging a rough coating made of CBPB, the base of the floor must be properly prepared. For example, if the material is laid on a wooden base, old or rotten boards must be dismantled and replaced with new ones

It is important to seal all cracks with putty, and the wooden base is primed for better adhesion to the glue on which the slab covering will be mounted.

If installation will be carried out on a concrete base, then it should also be carefully inspected for damage and repaired if necessary. Also, if there are strong horizontal deviations, leveling is done with cement mixtures. In the case of laying CBPB on the ground, it is necessary to first level the surface - this can be done by pouring it onto the ground sand and gravel mixture 20 cm thick and compacted it.

The process of building a gazebo with a DSP floor

The best option is to lay CBPB slabs on logs. In this case, if it is planned to install the foundation directly above the ground, supports for the logs are installed on the ground, and hydro- and thermal insulation is also laid. The distance between the supports can vary from 0.5 to 1 m - this indicator depends on the thickness of the timber used for the logs.

Materials and tools that need to be prepared for working with DSP:

• timber for logs (section 150x100 or 50x100 mm);
• DSP boards in the required quantity;
• antiseptic solution for timber;
• sawing tool (for example, a hacksaw);
• materials for waterproofing and insulation;
• tools for taking measurements (tape measure, pencil);
• fastening material;
• drill.

How to paint a DSP board

To give the DSP boards an attractive appearance most in a simple way is coloring. After appropriate preparation of the surface, apply two layers of paint using a roller or. Most often, in order to paint DSP, they use:

Acrylic paints . This paint has good adhesion and is highly wear-resistant. If financial capabilities allow, it is better to use paints that contain a solvent, but also water-soluble façade acrylic paints, if correct application, will last from 3 to 5 years.

Latex paint . This coating is resistant to alkaline and weak acid solutions, is easy to clean and mechanical cleaning with detergents. Besides. Painting works You can do it yourself, which will save you a significant amount.

Silicate paint . The use of this type of coating has high adhesion, their vapor permeability ensures optimal conditions for air circulation, which prevents the appearance of mold and other fungi. The coating is not afraid of atmospheric influences and detergents, and the service life will satisfy even the highest requirements.

Before you start painting DSP, it is necessary to take into account that the use of alkyd paints is undesirable, since direct contact with alkalis may cause cracking and peeling of the coating.

1 What are such slabs made of? Are additives needed?

DSP is a multi-component sheet building material, the manufacturing process of which uses Portland cement and wood shavings. In addition, the board contains special chemical additives that allow the basic materials to coexist without any problems. Indeed, under normal conditions, wood is not friendly with cement, which provokes excessive moisture and associated warping and rotting of the material.

Portland cement and shavings are used for the manufacture of CBPB

The use of special additives (up to 2.5–3% of the total volume) eliminates the negative consequences of the proximity of wood and cement, giving the DSP such useful properties of the first and second components as heat resistance and fire resistance. And because of percentage– 24% of wood accounts for 65% of cement – ​​the slab also acquires other positive traits: high strength, frost resistance, soundproofing properties, vapor permeability and complete ignoring of the material by both insects and rodents.

In addition, at the same time, a wooden and cement board demonstrates such qualities as resistance to fungi, moisture resistance, resistance to temperature shrinkage and compatibility with most finishing materials, which is explained by enviable adhesion. At the same time, chemical additives in CBPB are not environmentally harmful materials, since they do not contain either asbestos or formaldehyde.

Technical characteristics of DSP

During manufacturing, high-strength cement compositions are mixed with wood shavings of various fractions, water and a number of chemical reagents (for example, liquid glass or aluminum salts). By reacting with wood shavings, chemicals mineralize them, thereby increasing the strength and durability of the slab.

Multi-layering is the main quality of the slabs, guaranteeing their high quality and special strength. The structure of the slab is formed in such a way that large fractions of chips are located inside, and small fractions are located outside. After preparing the cement-bonded particle board, it is placed in layers in special molds under a press, from where the finished multilayer CBPB with a smooth surface on one side comes out.

DSP: the technical characteristics of the slab are such that it does not require the application of finishing putty. It is enough to paint the slabs after placement. In some cases, applying a thin coat of primer before painting will be sufficient.

DSP floors: laying nuances

In general, the installation of CBPB slabs is carried out in exactly the same way as the installation of OSB slabs.

When carrying out work, it is important to follow several rules, and then the base of the floor will be made of the highest quality possible: . wooden beam for lags it is necessary to treat them with compounds that prevent rotting

Special compounds can be replaced with machine oil;

• wooden beams for logs must be treated with compounds that prevent rotting. Special compounds can be replaced with machine oil;

Antiseptics for wood impregnation

• When installing slabs on a concrete screed, beams of a smaller cross-section can be used for logs - up to 50x50 mm. This will save useful space;
• when installing logs, you should monitor their level - it must be strictly horizontal;
• before installation, the CBPB boards are laid out along the joists - this will allow you to determine which of them need trimming if necessary;
• the glue must be mixed well before use;
• Compensation gaps along the walls will allow you to avoid deformation of the DSP base.

Another example of the use of DSP

DSP is a pretty good material if you use it to create a flat base. It is not difficult to work with it, but due to the large mass of sheets, it is better to get an assistant.

Installation features

Slabs based on a cement-bonded particle mixture are easy to process. For cutting you will need a hacksaw with fine teeth. Large teeth contribute to the formation of dust and make the edges of the part uneven, so this tool is not suitable for sawing CBPB.

When arranging a dry screed, a concrete or wooden covering is used as a base for the slabs. It is also possible to lay the sheets on a frame, the cells of which are pre-filled with insulating material (mineral wool, foam plastic, expanded clay, or another type of dry filler).

The plates are fixed with self-tapping screws or using an adhesive mixture. The glue must be evenly distributed over the surface of the material with a notched trowel, leaving no gaps. This will help avoid deformation of the material.

It is also important to generously fill the joints with adhesive to obtain a monolith. Self-tapping screws are screwed in at intervals of 35-50 cm

When cladding the external walls of a building with DSP, an installation method is used that involves arranging sheathing. Frame parts can be wooden or made of metal profiles. When choosing wood, it is recommended to pre-treat it with an antiseptic solution to protect it from premature aging and microbiological processes.

To create thermal protection for a home, it is recommended to lay thermal insulation material between the walls of the house and the DSP. Preference should be given to basalt wool, which has good vapor permeability (the walls will breathe) and high resistance to moisture (low hygroscopicity will prevent the absorption of moisture into the layers of the insulation).

Finishing of slabs made of cement-bonded particle board involves surface treatment primer composition, laying the reinforcing mesh and applying a layer decorative plaster. The facade is painted in a color that echoes other architectural elements of the exterior.

Arrangement of the floor using DSP

Let's consider the arrangement of a floor made of cement-bonded fiberboard on joists using the example of a balcony.

Step 1. A layer of insulation is placed under the joists. The logs are installed parallel to the walls at a distance of about 30-40 cm from each other.

The joists are installed on top of the insulation

Step 2. Cross bars are installed and the sheathing is created. Between themselves wooden blocks connected using metal corners and self-tapping screws.

Cross bars installed, sheathing ready

Step 3. The space between the joists is filled with insulating material.

Laying insulation

Step 4. DSP slabs of the required sizes are laid across the longitudinal joists. The width of the piece of material should be slightly less than the width of the balcony (by 5-10 mm).

Laying CBPB boards

Step 5. The slabs are fastened with self-tapping screws to the joists. The gaps between the DSP boards are sealed with an adhesive composition.

DSP in the process of creating the foundation

Slabs based on cement and shavings can be used to create formwork, which helps when pouring the foundation. The thickness of the material depends on the required dimensions of the foundation and ranges from 16 to 26 mm.

Strengths of DSP formwork.

The ease of installation of slabs reduces labor costs by an order of magnitude and shortens the time required for work, thus reducing the cost of pouring the foundation. On outside you can apply a special paint, after which it will acquire the properties of vertical waterproofing. Due to the high strength of the slabs, the formwork is resistant to deformation during pouring and drying of the concrete solution.

The versatility of DSP allows this material to be used in the construction of housing based on a frame, for leveling floor and wall coverings, as well as during the installation of soft roofing in buildings of any type. DSP flooring boards receive good reviews from builders around the world due to the high quality of the material and excellent characteristics.

Cement particle board application for flooring

The main advantages of DSP are considered to be high strength and durability

The use of building materials is to lay ready-made panels on various types of grounds:

• a flat surface of a wooden or cement floor;
• wooden logs installed at equal intervals.

Ceramic tiles can be glued to the surface of the slabs, flooring can be laid, and laminate or parquet can be laid. The properties of the material are preserved for decades, provided that the installation technology is followed.

Scope of application of CBPB boards

As mentioned above, CBPB boards, the use of which provides high mechanical strength created structures, are widely used in construction, repair and finishing works ah, in particular:

• In the manufacture of formwork foundations and other monolithic reinforced structures. The use of DSP significantly simplifies the installation process; in addition, this design prevents concrete leakage and ensures the formation of smooth side walls that do not require subsequent plastering.
• When covering walls and erecting . In most cases, DSP sheets are attached to a pre-assembled metal or wooden frame. The thickness of the sheets in this case ranges from 8 to 12 mm. For fastening, self-tapping screws are most often used; it is also possible to use screws or nails as fasteners. In some cases, when leveling walls, special adhesive polymer mixtures can be used.
• Application of DSP boards for flooring provides high mechanical strength, as well as high thermal, hydro and sound insulation. The thickness of the material is selected based on the current loads and the distance between the lags, however, the use of CBPB boards with a thickness of less than 14 mm is not recommended.
• Application for facade at home allows not only to significantly reduce the time required for work on exterior decoration, but also provides high-quality waterproofing main walls. Another advantage is that when using DSP, the characteristics of the material allow you to create various types of ventilated facades. As for the sheet thickness, for outdoor use it can vary from 12 to 14 mm.

Slab production

The production of CBPB consists of the following stages:

1. Aluminum, liquid glass, and various salts are included in aqueous solutions that are loaded into special mixers.
2. Mineralization of raw materials occurs with the gradual introduction of wood chips, consisting of different-sized fractional inclusions, into these solutions.
3. Then cement and a little water are added to the composition.
4. The mass is thoroughly mixed to obtain a homogeneous consistency and sent under a powerful press.
5. The result is a thin but durable product with a smooth surface.

The smooth surface of the slab is obtained due to the special distribution of chips in its structure - larger fragments are located inside the product, and small ones are on the surface. During the production of CBPBs, there are no voids in them. Another advantage is that the product is not subject to additional leveling, but can be immediately used to make a subfloor and serve as a high-quality, flat base for laminate, tiles and other types of finishing coating.

DSP production technology

From the name itself it becomes clear that the main components of this material are cement (65%) and wood shavings (24%). All this is mixed with water (8.5%), and various additives are added to the resulting mixture to improve the technical characteristics of the slab (2.5%).

Two types are used in the production process of CBPB boards: chip material. They differ in size: small and medium. The slab itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. The production process itself takes place in the following sequence.

• The shavings are mixed with hydration additives.
• Cement grade M500 is added to the resulting mixture.
• Water is pouring in.
• The solution is thoroughly mixed until a homogeneous mass is obtained.
• The first layer of fine chips is poured into the mold.
• The second layer with medium-sized shavings.
• And the third layer.
• Pressing is in progress.
• After which the semi-finished material is heated to +90C for eight hours.
• Then it is dried under natural conditions for 13-15 days.
• After which, depending on the batch, it is either polished or simply stored.

Cement particle boards used in construction

DSP is a cement-bonded particle board, and the name fully reflects the composition of this material. DSPs are made from a mixture whose components are wood shavings and cement compounds.

What are DSP and OSB? What is the difference?

The building materials include:

• wood shavings with fractions of various sizes – 24%;
• water – 8.5%;
• special additives – 2.5%;
• Portland cement – ​​65%.

DSP boards for external use

The production process is quite simple - DSP is made as follows.

1. Special aqueous solutions are loaded into special mixers, which include various salts, liquid glass and aluminum.
2. Next, wood shavings with fractions are gradually added to these solutions different sizes– mineralization of raw materials occurs.
3. Cement is mixed into the resulting composition and a little more water is added.
4. The mass is thoroughly mixed until smooth and then goes under a powerful press.

GOST 26816-86

The result of this production chain is a finished cement bonded particle board, which is quite thin and has a smooth surface. And a large amount of cement in the composition allows you to create quite durable material. By the way, inside the slab the chips have O larger dimensions than the outside, due to which the smoothness of the surface of the finished material is achieved. DSP does not need to be further leveled after installation, making the material excellent for creating a rough floor covering for laminate, tile and other types of finishing. Also, no voids are formed inside the DSP during production.

Production of cement particle boards

On a note! Wood shavings are also used as a raw material in the production of chipboard, fiberboard and OSB boards. The technologies for producing these materials are somewhat similar to the technology for producing CBPB boards.

Comparative table of performance characteristics of wood-based panel materials

DSP boards are widely used in construction. They can be used for finishing façade walls houses, from which various partitions are created indoors. The material is suitable for use for restoration purposes and for interior finishing work. Moreover, it is suitable for both apartments and private houses.

DSPs are used in construction for many purposes

The DSP board is characterized by high environmental friendliness, as it is created from natural natural materials and contains virtually no additional chemical ingredients. That is why the stove is recommended for use both in residential premises and in production.

Cement particle board (CSP)

Using a cement bonded particle board is an opportunity to avoid the labor-intensive pouring of cement screed to create a base. Building materials allow you to reduce labor costs and spend less funds from the budget planned for leveling floors for laying the finishing coating.

Installation of a DSP board under ceramic tiles

Rules for processing what can be used to saw and drill CBPB boards

Whatever one may say, CSP is a concrete stone filled with shavings (wood filler). Therefore, when the question is raised about how to process the material of this type, hand tools cannot be mentioned. Cutting and drilling can only be carried out with electric tools.

In this case, it is better not to use a jigsaw, although some craftsmen manage to cut thin slabs with this tool. You just have to change the file often - every 5-7 m. Therefore, the optimal solution is a disk cutting tool.

The easiest way to cut CBPB is with a circular saw with a diamond blade.

As for the disk, there are two options:

1. Diamond coated disc with cut out segments. This disc is used for dry cutting. Here you can use discs for cutting stone, concrete or brick - they will all work.
2. Discs coated with pobedite, used for cutting wood. DSP is not the strongest material compared to stone, so this tool can handle it.

As for power tools, most often craftsmen use an angle grinder or a circular saw (parquet).

Attention! It is easier to cut CBPB boards with a circular saw because the power tool has a support bar. It is this that allows you to clearly orient the disk in a plane perpendicular to the sheet, and the final result is an even cut of the material

DSP boards can be cut with a grinder with a diamond cutting disc installed on it

As for drilling holes in slabs, either metal drills or pobedit drills are used for this.

Types and characteristics

There are 3 types of DSP:

• fiberboard– heat-insulating material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to impact biological factors;
• wood concrete– made from sawdust and small shavings. Has a wide range of applications (thermal insulation, finishing, material for wall partitions etc.);
• xylolite(slab and cast). It has high strength, thermal insulation qualities and a wide range of colors, and is used as a floor covering.

Due to their water absorption, the slabs increase in size, so when installing, a gap is required between them

Kinds

There are three types of DSP. Studies of the material have accurately shown that each of them does not lose its valuable properties even during multiple cycles of significant temperature increases and subsequent defrosting.

Resistance to fire and particularly humid environments, as well as negative biological factors, was also confirmed. But each type of slab has its own characteristics, consisting in the production method, the difference in source materials, characteristics finished products and scope of application. Among the types you can indicate.

1. Fiberboard. Its basis is the so-called wood wool, which is long-fiber shavings. The composition also includes inorganic binders.

Received on special machines wood strips are impregnated with solutions of calcium chloride and liquid glass. The raw materials are pressed into molds and subsequently dried. The thickness of such slabs can reach 150 mm, but there are a number of much thinner parameters.

These building elements, with their considerable strength, are excellent for thermal insulation. A similar material is also used as an acoustic material.

It is easy to process and soft, for this reason it is in demand for multifaceted repairs, as well as reconstruction work of various structures. During construction operations with slabs, due to their low weight, lifting equipment is not required, and therefore their use is very economical.

2. Wood concrete. It is classified as lightweight concrete and contains small shavings, sawdust, reed chaff or rice straw. The highest quality slabs of this variety are made from wood chips.

If the basis of the composition is wood shavings, then the material is usually called wood concrete, if sawdust - sawdust concrete. The two types mentioned have slightly reduced performance characteristics compared to the first one mentioned above.

They are heavier, denser and subject to unpleasant deformations, but they are also somewhat cheaper. The scope of application of wood concrete is quite wide. But mainly it is in demand as a material for low-rise private construction, especially popular in the manufacture of wall partitions, also for finishing and thermal insulation.

3. Xylolite is most often known in application as a coating. DSP for flooring. Plates, similar to those previously described, are made from wood waste, differing from other types in production technology. On sale, the presented assortment pleases with a variety of colors.

The material is distinguished by excellent thermal insulation qualities and increased strength. It does not burn in an open fire, but only gradually chars; even when boiling, it does not get wet in water and is only slightly thermally conductive; It has enviable elasticity and is hard like stone, but at the same time it is easily processed like wood: drilled, planed and sawed. In addition to the above, it is ideal for use as cladding for stone, covering stairs, window sills, and roofs.

An important characteristic is the weight of the DSP board. Such indicators are simply necessary to know during construction and other work.

The specified data is very useful during cargo transportation and during installation work. The mass of one module directly depends on the thickness and, knowing this indicator, it is easy to calculate. After all, for every 10 mm there is approximately 54 kg of tile weight.

Installation work: how to cut DSP

You shouldn’t try to cut CBPB with a hacksaw - it’s a thankless task, the process is long, and the result leaves much to be desired. You can use a jigsaw or grinder.

Article

DSP board (cement particle board)- a popular construction and finishing material consisting of wood chips, Portland cement, water and special additives that provide the necessary performance characteristics.

The slabs are made by pressing. The result is durable sheets with smooth surfaces and ends, which allows you to significantly save time during their installation. This non-flammable material, therefore it is recommended for widespread use in construction.

DSP is used:

• as cladding of columns, internal and external cladding of walls, cladding of entrance doors
• for the construction of moisture-resistant partitions and wall cladding in wet rooms
• as a front covering for floors, ceilings, window sills, creating a base for roofing
• as permanent formwork for building foundations

Technical characteristics of cement bonded particle board

DSP, whose technical characteristics are among the best among wood-based panel materials, is widely used in construction, agriculture and other areas of our lives. In this table you can see the main technical characteristics of cement bonded particle boards.

Advantages of DSP

• Environmental friendliness. Cement particle boards do not emit toxic substances into the atmosphere and do not contain components hazardous to human health.
• Fire safety. Does not spread combustion and does not ignite within 40-50 minutes of exposure to fire.
• Compatible with other materials. The DSP sheet has a smooth surface, so you can lay tiles on top of it, glue wallpaper, or paint without prior leveling.
• Water resistance. The material has low water absorption and retains its original dimensions after drying.
• Biostability. Not susceptible to mold and mildew, does not attract insects and rodents.
• Durability. The material has high mechanical strength and retains performance characteristics for at least 50 years.

Dimensions of DSP

Look at the sizes and thicknesses of the CBPB sheets:

Where to buy cement bonded particle boards

DSP boards can be purchased at our warehouse complexes in Moscow and the Moscow region. You can order delivery of material with payment on the spot. It is possible to form prefabricated machines with

The construction of modern buildings requires increasingly advanced, versatile, high-quality and inexpensive materials. One of the latest developments in this direction is CBPB, which can roughly be called an improved version of particle boards.

Cement particle board as a building material

Cement particle board, which appeared on the building materials market relatively recently, has already been appreciated by many developers. Thanks to excellent operational characteristics, with its help, dry installation of structures is carried out in buildings for various purposes.

DSPs are manufactured using the pressing method. Solid shavings tree species(its share is 24%) is mineralized under the influence of special hydration additives (2.5%), after which Portland cement (65%) and water (8.5%) are added to it. As a result, a monolithic smooth slab emerges from the press, consisting of several layers with large fractions on the inside and small ones on the outside.

Types and characteristics

There are 3 types of DSP:

• fiberboard– heat-insulating material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to biological factors;
• wood concrete– made from sawdust and small shavings. It has a wide range of applications (thermal insulation, finishing, material for wall partitions, etc.);
• xylolite(slab and cast). It has high strength, thermal insulation qualities and a wide range of colors, and is used as a floor covering.

Due to their water absorption, the slabs increase in size, so when installing, a gap is required between them

Pros and cons of slabs

The high popularity of DSPs is explained by their many advantages:

• if the installation was carried out in accordance with the technology requirements, The service life of the slabs can reach 50 years. Research results have shown that the material does not lose its beneficial properties even after repeated cycles of freezing and thawing. The boards also showed high resistance to moisture, fire and biological factors;
• multilayer structure provides high tensile and compressive strength characteristics of CBPB, which allow you to strengthen frame structures using slabs;
• slabs are often used as insulation, which is explained by their good heat and sound insulation qualities;
• processing the material is not particularly difficult. He easy to drill and cut, his Smooth surface excellent for applying putty, plaster and adhesive compositions, thanks to which the slabs are successfully used in the decoration of premises;
• exact dimensions of the slabs significantly speed up the installation process;
• the front side of the DSP can have not only a flat, but also a corrugated surface. This ensures a variety of room design;
• ecological cleanliness;
• relatively low cost.

There are significantly fewer disadvantages of cement-bonded particle boards:

• heavy material weight(about 14.5 kg per square meter), which significantly complicates the installation process. This is explained by the high density of CBPB (up to 1400 kg per cubic meter);
• low strength indicators bending, which sometimes leads to breakage of the slabs.

Scope of application

These slabs are used in large and private construction. They are used to build houses, utility rooms, use them indoors and outdoors, and even make furniture. The thinnest slabs (from 10 to 16 mm thick) are used for cladding the internal and external walls of buildings for various purposes. For fastening, it is necessary to first make a sheathing from wood or a metal profile. In addition to aesthetic This design can also serve thermal insulation purposes.. In this case, the space between the DSP and the wall is filled with insulation. This method is often used to modernize old buildings. Its advantages are simplicity and relative low cost. The permissible gap between the plates is up to 1 cm. The joints are sealed and overlays are attached over them.
The same DSP (up to 16 mm) also used for the manufacture of internal partitions. Thanks to high performance moisture resistance, they are often installed in bathrooms and other similar rooms. The slabs are pre-primed, the surface and edges are treated with water-repellent materials. They are also used to produce balcony railings, cladding for fire-resistant doors, etc.

You can even make furniture from the best grades of DSP

From DSP from 12 to 24 mm perform permanent formwork for foundations in low-rise construction. The high strength of the slabs prevents their deformation when pouring the mortar. Another advantage of the design is its simplicity. If the DSP is painted or covered with a waterproof material, they can serve as vertical waterproofing.
Window sills made of cement-fiber boards fit perfectly into any interior. They have all the advantages of wood products, but at the same time they are much cheaper. The thickness of the slabs used for the production of window sill boards is 24-36 mm. They are not subject to deformation, durable, monolithic and affordable.
When arranging floors Cement particle boards successfully replace chipboards. If a floor made of CBPB is laid on logs, then the distance between them should be within 60 cm, and their cross-section should be at least 5x8 cm. CBPB from 16 to 36 mm in thickness can act as a base, underlying, leveling or finishing layer with a front finishing. In some cases, they are used instead of cement screed, as well as in the construction of prefabricated floors on bulk soils (CBF slabs for floors with a thickness of 24-36 mm).
A base for a soft roof can be made from DSP. For this work, 16-24 mm slabs are used.

Installation methods

DSPs can be mounted in various ways depending on the purpose for which they are used. When finishing or insulating buildings, they are attached to the sheathing, made of metal profiles or wooden blocks, with self-tapping bolts or nails. The installation of permanent formwork also involves erection of the frame (given the large weight of the slabs, it, like the sheathing when finishing the walls, must be strong enough). In addition, the slabs can be laid on joists (when installing the floor) or rafters (under the roofing). For interior decoration they are also can be attached to the wall with mortar or mastic.

Release form and cost

DSP is sold in sheets packaged in bundles. Panel thickness varies from 8 to 36 mm. Dimensions can be (in mm): 2700x1250, 3200x1200, 3200x1250 and 3600x1200. The number of sheets in a pack depends on the dimensions.
The cost is set per square meter or per sheet. In the first case, it depends only on the thickness, in the second - on all panel parameters. The sizes of CBPB slabs for walls differ from those used for floors, but the price is approximately the same. Price square meter 8 mm DSP from different sellers starts from 150-250 rubles. The most massive slab (36 mm) will cost about 4-5 times more.
According to their own beneficial properties(except, perhaps, only for the weight) DSP is in no way inferior to its wooden counterparts and even surpasses them. And the versatility of the material combined with affordable price make it practically perfect choice for construction and finishing works.
