What does it mean to see cockroaches in a dream - interpretation for women

Cement particle board (CSP) is a versatile building material suitable for both indoor and outdoor use. Moreover, in terms of the sum of its characteristics, it surpasses any wood-based sheet material (chipboard, OSB), because, in addition to high heat and sound insulating qualities, as well as enviable strength, the DSP board demonstrates acceptable fire resistance and the complete absence of warping or shrinkage. Thanks to this, DSP can be painted, plastered, finished with ceramics (tiles) or siding.

What are such plates made of - are additives needed

DSP is a multi-component sheet building material, in the manufacturing process of which Portland cement and wood shavings are used. In addition, the composition of the plate includes special chemical additives that allow the base materials to coexist without any problems. Indeed, under normal conditions, wood is not friendly with cement, which provokes excessive moisture and the associated warping and decay of the material.

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 CBPB such useful properties of the first and second components as heat resistance and fire resistance. Moreover, due to the percentage ratio - 24% of wood accounts for 65% of cement - the plate acquires other positive qualities: high strength, frost resistance, soundproofing properties, vapor permeability and complete disregard for 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 DSP do not belong to environmentally harmful materials, since they do not contain either asbestos or formaldehyde.

What are the specifications and sizes

Domestic enterprises have been producing the first DSP boards for floors and walls since the late 1980s. Now this composite building and finishing material is produced at six enterprises, adhering to the following size range:

Length - from 2.7 to 3.2 m. Moreover, the most popular plates are 3 meters long.
Width - exactly 1.25 m. This size is a kind of standard that determines the step of the crate when finishing the surfaces of the DSP.
Thickness - from 8 to 36 mm. Moreover, this parameter divides the range into 7 sizes, and the depth of the most popular sheets is 10, 16 and 20 mm.

The thickness and length of the sheet affect such a value as the weight of the DSP. Moreover, an 8-mm slab 2.7 meters long weighs the least - 36.45 kg, and a 36-mm slab 3.2 meters long - 194.4 kg will have the maximum weight.

Other technical characteristics typical for the DSP board are as follows:

Density - from 1.2 to 1.4 t / m 3. The difference in density depends on the level of humidity, which can be unstable (standards allow fluctuations within 3%).
Strength - bending 9-12 MPa, tensile - 0.4 MPa. As you can see, the plate reacts poorly to both bending and stretching. Another thing is longitudinal deformation. In this case, the resistance of the DSP is so great that it can be used to strengthen the load-bearing wall of the house.
Standard humidity is 9%. Moreover, after a daily stay in water, this indicator increases only to 16%, and the linear dimensions of the sheet change by 0.3% in length and 2% in thickness.
Vapor permeability - 0.03 mg / (m h Pa). Due to the porous structure, cement-bonded particle boards are classified as "breathable" materials, which, combined with the general environmental friendliness of the base, increases the attractiveness of this option in the eyes of builders of healthy dwellings.
Thermal conductivity coefficient - 0.26 W / (m K). Such a sheet cannot be compared with pure wood (0.15), but compared to brickwork (0.7), cement-bonded particle boards look very dignified, and compared to pure concrete (1.75), they are completely amazing.

However, no matter what technical characteristics the DSP plate demonstrates, the use of this material is associated with solving a narrow set of tasks that will be discussed below in the text.

Disadvantages of cement and chip slabs - what are they

After reviewing the characteristics, I would like to mention the disadvantages of the DSP. First of all, these include the significant weight of the sheet, which makes it difficult to transport the panel to the upper floors or roof. However, for the formation of a roofing cake, 10- or 16-mm sheets are usually used, the weight of which does not exceed 75-85 kilograms, which is quite acceptable for a roofing team of 3-4 people.

The second serious disadvantage of DSP is its low bending strength. Such plates are not suitable for the construction of arches and other architectural forms with curved lines. However, if necessary, the same OSB sheet can replace the cement particle board.

The practice of application in outdoor work - where it is useful

Due to the high frost resistance and acceptable moisture resistance that any cement-bonded particle board has, the use of this material in outdoor work will be justified even if thin, 8 mm sheets are used. DSP is used in the construction of ventilated facades. In this case, lighthouses are stuffed onto the wall of the building, on top of which sheets of cement and shavings are laid. Further finishing depends on the degree of grinding of the outer side of the panel. Unpolished material can be covered with plaster, not forgetting the reinforcing mesh. The sanded sheet is usually painted or left as is.

In addition, due to the high moisture resistance of DSP, the use of this material is also possible in the context of the base for the assembly of removable or fixed formwork. High stiffness, minimal moisture warpage and virtually water tightness make this material an ideal formwork for reusable or single use. Moreover, the sheets are easily processed, allowing you to assemble structures of even very complex configurations. And as a fixed formwork, DSP has an additional advantage - the sheet will work as a waterproofing agent, simultaneously insulating the base.

Sandwich panels based on sheets of chips and cement are also very popular. Such building materials allow you to assemble a house in a matter of months. In this case, the main advantage of DSP is the thickness of the sheet, which reaches 3.6 centimeters and allows you to increase the overall rigidity of the structure. Therefore, from sandwiches based on such sheets, it is possible to build houses of virtually any number of storeys. True, a sandwich panel made of a heavy-duty sheet with a thickness of 36 mm weighs more than 400 kilograms, which somewhat complicates the construction process.

DSP boards are used not only for floors or attic floors. In this case, the panels are used as cladding, they are stuffed onto the frame racks with a preliminary vapor barrier. Moreover, from the outside, the slab is first primed, raising the adhesion of the surface, and then painted or plastered, obtaining an outwardly attractive facade. Well, the internal layer of mineral wool located between the racks of the frame will be responsible for the thermal insulation in the frame house, so the heat resistance of the DSP in this case can be neglected.

Interior decoration and floor arrangement - for every taste

If you have a DSP board, the use of this material in interior work is limited only by your imagination. From the sheets, a high-quality rough sheathing for walls or a frame is obtained. Moreover, they can be covered with a layer of plaster or primer and wallpapered or tiled, so DSPs go to wet areas (bathrooms, showers, toilets, kitchens), and to ordinary rooms. Thick sheets can be used in the arrangement of interior partitions.

Moreover, 24- or 36-mm panels are used even without a frame. They are folded in 2 or 3 sheets, fixing to the ceiling and floor.

Such a move allows you to speed up the arrangement of the interior, and thanks to the wood base in the DSP, you can not only screw in self-tapping screws, but also hammer in nails, hanging pictures, mirrors, shelves or decor. DSP in the interior is valued for its high fire resistance. This material not only resists an open flame for 50 minutes, but also does not emit toxic combustion products. Therefore, such panels are classified as a low-combustible type of building materials G1 - under no circumstances will the DSP burn on its own.

However, the most common scope of such plates is interfloor, basement or attic floors. DSPs for floors or ceilings are more than willing to buy. This material can be used to insulate a concrete slab, strengthen the frame floor, and increase the moisture resistance of a wooden base. Installation of the floor (basement) based on DSP involves the following operations:

Waterproofing and soundproofing are laid on the supporting column.
A log (beam 5x8 centimeters) and cranial bars are laid on top. The placement step is 60 centimeters.
A boardwalk or a thin DSP slab is mounted on the bars - the use of thick slabs for a rough-type floor will be unjustified for practical reasons. After all, the draft floor holds only a heater.
A waterproofing membrane and a layer of insulation are laid on top of the flooring. Moreover, the thickness of this layer should be 2-3 centimeters less than the depth of the log - this space will go under the ventilation gap.
At the end, a DSP sheet is laid on the log and fixed to ordinary self-tapping screws with a countersunk head.

By acting in this way, it is possible to obtain a warm floor with excellent strength characteristics even with a 20 mm thick cement-bonded sheet. Panels with a thickness of 24-36 mm can be laid on sand-cement bedding or compacted clay, refusing to support posts. For residential buildings, this technology is not suitable, but for warehouses, a thick cement-bonded particle board, the technical characteristics of which indicate a readiness to withstand a large operational load, will come in handy.

The floor in the house and apartment should be even and warm. This can be achieved by pouring a screed, but it is easier to lay sheet material with suitable characteristics on the subfloor. One option is a DSP board. It is a durable non-combustible material that can be used for leveling, as a base for flooring.

DSP plate - sheet material for exterior and interior decoration. It can be used on walls, ceilings, roofs, as a subfloor, as a base for flooring. The composition of the DSP is wood chips and cement with additives.

Portland cement brand M500 - 60-65%;
wood (wood) shavings of medium and fine fraction - 24-25%;
water - 8.5-10%;
additives (calcium chloride, aluminum sulfate, aluminum sulfate, aluminum chloride, sodium silicates) - 2-3%.

The DSP board is formed from three to four layers. The inner layers in the DSP are made of sawdust of greater length (the thickness of the sawdust is 0.2-0.3 mm, the length is 10-30 mm), the outer layers are made of finer ones. The inner layer serves to give strength and elasticity, the outer layer allows you to make plates with a smooth surface that requires minimal finishing. Formed sheets are fed into the press, then dried to normal moisture content (10-12%).

Characteristics

Cement particle board has the following characteristics:

As you can see, the characteristics of DSP boards are good. Another positive point - the high density of the material leads to the fact that the screws in it hold well. Specific pull-out resistance 4-7 N/m. This is higher than that of fiberboard and, even more so, than that of. But in order to install fasteners in very dense sheets, you have to pre-drill holes. And if it is necessary that the hats do not stick out, then countersink.

Important properties

At its core, cement particle board is a hardened cement mortar in which chips are used as a reinforcing substance. That is, the material is harmless in terms of environmental friendliness. It can be cut with different tools. A hacksaw is difficult and slow, a special saw for concrete is needed in a jigsaw, but an angle grinder (grinder) is cut quickly, but the process is very dusty. If there is a need, it is well milled.

The DSP plate is not affected by fungus and insects. Can be glued with wood, metals and polymers (plastic). If necessary, two layers can be laid one on top of the other. If you want to have a monolith, use cement-based tile adhesive.

One of the important aspects is low flammability. Not a fireclay brick, of course, but when exposed to high temperatures it slowly chars, then crumbles.

Application area

If we talk about the advantages of DSP, first of all it is worth mentioning the incombustibility of the material. It does not ignite and does not support combustion. The second positive point is the absence of synthetic components that emit styrene and formaldehyde. This explains the popularity of this material in frame housing construction. Even despite the solid weight of the plates, they are used to make the lining of the first and second floors.

Scope of DSP boards - walls, ceiling, floor, formwork

A DSP slab for the floor is also used. But it is worth saying that the material has an unstable geometry. This is explained by technological features. So getting a perfectly flat surface without "steps" between the sheets is difficult.

Second moment. DSP boards are plastic. In the sense that if they are laid on an uneven surface, over time they will take the shape of the surface. On the one hand, this is good - where some sheet materials can break on uneven floors, the DSP will simply repeat the shape. On the other hand, you can’t even put a thick sheet on logs with a large distance - it will sag over time. On a subfloor or other base with minimal gaps, it can be used without problems.

DSP on the floor: how to use

The floor of DSP is recommended to be made from slabs with a thickness of at least 20 mm. Theoretically, plates of this thickness can also be placed on logs, but it is better to make their installation step small. Thinner sheets can also be used on a solid, even base (concrete screed or subfloor), but the heat-insulating and sound-proofing characteristics will be lower.

As a base for laying the finish coat - this is one of the good options. It is possible to lay both soft (linoleum, carpet, PVC tiles, cork) and hard (laminate, parquet, parquet board) coatings. Lay on the DSP and tile. In this case, take cement-based glue and see that the base is stable, there is no movement. When laying out, try to make sure that the seam of the tile does not fall on the junction of two sheets.

Under hard coatings (in particular, under tiles), it is possible to lay DSP not along the walls, but obliquely. Thus, with a straight layout, you will definitely avoid the coincidence of the seams. There is more fuss with such laying of plates, but the load on the seams will be lower. Less chance of cracking at the seams or broken tiles, swelling of the laminate seam.

How to seal the joints of the DSP

Since the cement-bonded particle board has thermal expansion, the boards are laid not close to each other, but with a gap. Under a hard floor covering, joints can be left unsealed (open seam). The seams should fall on the base (beam, logs, crate), because the joint will not be empty. For better insulation, a strip of waterproofing material is laid on the beam with an open seam. It can be a dense polyethylene film, roofing felt or more modern waterproofing materials.

If the floor of DSP boards is made under a soft floor covering, the seam is filled with an elastic sealant. When choosing a sealant, pay attention that after drying it remains elastic, otherwise it will simply crumble and sag. It must also be compatible with wood and cement. The best copolymers in this regard, but they are expensive.

There is another option for filling the joint of DSP boards on the floor - an elastic cord made of polyethylene foam. It is laid in the gap, and on top it can be covered or painted.

How to fasten and fastener installation step

DSP can be fixed with nails or self-tapping screws (self-tapping screws). The selection of fasteners depends on the thickness of the plate. The length of the nail or self-tapping screw must be at least three times the thickness of the plate. For example, fasten a 16 mm thick slab. The length of the screw or nail is 48 mm or more (16 mm * 3 = 48 mm).

Fasteners are installed:

along the perimeter of the sheet;
along the cross beams.

Along the perimeter of the sheet, self-tapping screws or nails are set back some distance from the edge. This distance, as well as the installation step, depends on the thickness of the sheet. All data are shown in the table above. These are the maximum allowed distances. For the floor, this is not as critical as for mounting on vertical surfaces, but, all the same, it is possible to install fasteners less often, more is undesirable.

two layers

When installing floors on a rigid base (wooden floor, subfloor, concrete slab), it is recommended to lay two layers of sheets. Their total thickness and the thermal insulation materials used (if any) must provide the required level of thermal insulation and sound absorption.

In this case, the second-row DSP slab is laid with offset seams. The offset of the seams must be at least 50 cm. The layers can be twisted together with self-tapping screws. If you smear them with glue, it will be almost a monolith. This, by the way, is a way out if it is difficult to lift thick slabs to a height. Thinner ones can even be carried up the stairs.

Do not forget to leave a gap for thermal expansion along the perimeter of the room - it is 3-6 mm. In order to leave a gap along the walls when laying the DSP, you can support it with mounting wedges, insert gaskets between the wall and the edge of the sheet. Insert thickness - 4-6 mm. Can be rolled around the perimeter. It will also improve the thermal and sound insulation characteristics. If the budget is limited, you can cut thin foam into strips and lay these strips along the walls.

Underfloor heating from DSP slabs for tiles.

The construction industry is one of the most actively developing today. Periodically, new technological solutions appear on the building materials market. One of such innovations is DSP boards, the sizes and prices of which have greatly pleased both specialists in this field and ordinary consumers. Today, together with HouseChief experts, we will try to figure out what is the uniqueness of this building material, what are its positive qualities, and whether it has disadvantages.

What is a CSP

The uniqueness of the sheet building material, which was briefly called CSP (cement-bonded particle board), lies in the fact that it was possible to combine seemingly incompatible components in its composition - Portland cement and crushed wood shavings. This became possible due to the introduction of special hydration additives that neutralize the harmful effects of the components included in the composition of the plates on each other. Modern manufacturers have learned how to make plates without the use of phenol and formaldehyde harmful to human health.

Technically, the process of manufacturing plates is as follows:

The raw mass is formed in a special drum, where wood shavings, mineral components, Portland cement, and water are successively added.
The formation of the plate occurs in layers, while finely ground chips are located outside, and larger chips are inside the product, thereby ensuring its strength. The smoothness of the front layer is achieved due to small chips.
Moving along the conveyor line, the workpiece enters the hydraulic press, where it is molded under high pressure.

The ideal smooth surface allows even or even walls. If you veneer the house with panels and paint them in one of the pastel colors, you will get a classic facade, where the main role will be played by decorative strips covering the joints between the panels.

Water-repellent properties have made products based on chips and indispensable for finishing wet rooms.

Specifications, application of DSP boards

Water absorption should not exceed 16%.
It is allowed to change the linear dimensions at high humidity (6-12%) in width by no more than 2%, in length - by 0.3%.
The bending strength should be: 12 MPa - for panels with a thickness of 10, 12 and 16 mm, 10 MPa - for plates with a thickness of 24 mm and 9 MPa - for plates of 36 mm.
The strength of the plate under perpendicularly applied tensile loads must be at least 0.4 MPa.
Soundproof properties are 45 dB.
Thermal conductivity - 0.26 W / m × ° C.
According to GOST 7016-82, the value of the roughness level after factory grinding should not exceed 80 microns. For untreated slabs, this figure is 320 microns.
The material belongs to the group of low-combustible products (G1).
For dry rooms, the service life is 50 years or more.

Important! It is recommended to use a carbide-coated concrete and stone cutting blade designed for this type of work. To prevent the tool from failing quickly, the rotation speed should be at least 200 rpm.

Finishing the facade of the DSP

Houses, the facades of which are lined with CSP, acquire an aesthetic appearance. The front layer of such products can have different designs. They imitate other finishing materials (stone, brickwork, milled decorative slabs for stone and brick

The use of DSP for the floor

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

Mounting on logs Preparatory work before laying the DSP on the floor

Fixation of the plates is carried out using self-tapping screws, while the screw with a countersunk head must be immersed in the body of the wooden beam by 20 mm. The result is a perfectly flat subfloor with excellent performance.

frame construction

DSPs have proven themselves in the construction of frame-type houses. There are two options - the purchase of a ready-made house kit based on DSP or the independent construction of walls, between which there is a mineral insulation. The slabs are fixed on a wooden or metal crate, while the frame is sewn around the perimeter, and then the House is cut out using frame technology using DSP

When performing construction and finishing works, the most important aspect is the reliability and durability of the resulting structure, but not all materials provide such parameters. That is why a cement-bonded particle board with the necessary performance characteristics is an excellent solution. Products have their own characteristics, which should be taken into account in order to achieve the best result.

Deciphering DSP - cement-bonded particle board. The products include the following components:

High grade Portland cement (from M400) - 65%.
Wood chips (most often coniferous) - at least 24% of the total mass.
Water without impurities - 8.5%.
Special mineral additives (sodium silicate, aluminum sulfate and others) - 2.5%.

The availability of the constituent cement-bonded particle boards determines their high popularity.

The products belong to composite materials and have been known for quite a long time, which is confirmed by GOST 26816-86. For a long time it was unclaimed due to the wide variety of the construction market.

At the moment, the manufacture of the material is regulated by GOST 26816-2016. This regulation is based on the 1986 document and the European standards EN 634-1:1995 and EN 634-2:2007. Although the demand for products is increasing, due to the excellent quality and reasonable price, its availability remains rather low.

Material production

The plate manufacturing technology includes a number of successive stages:

Modern production is constantly developing, so it is possible to obtain DSP sheets with a minimum thickness of 6 mm without loss of properties.

Advantages and disadvantages

The material stands out among the rest with many advantages:

But the DSP plate also has disadvantages:

When buying, pay attention to the availability of safety certificates.

Types of cement particle boards

The panels have a similar composition and allow you to choose the right material for a particular situation:

The characteristics of xylolite and fibrolite are very different, therefore their purpose is different.

Xylolite. The base contains shavings and magnesia cement. It has high strength, so it can be used as a floor covering.
Fiberboard. For production, wood raw materials that have undergone special processing and burnt magnesite are used. Portland cement is used as a binder. The resulting parts are soft and suitable for thermal insulation.
Arbolit. Quite a popular variety for outdoor and indoor use.

The use of new technologies made it possible to bring "Arbolit" to the leaders of sales

It is also customary to divide parts according to the area of \u200b\u200buse, depending on the thickness. There are two brands of products: TsSP-1 and TsSP-2, which differ in parameters.

Specifications

Such a facing material has the following properties:

Bending strength. From 9 to 12 MPa. This indicator indicates that the laying place should be even. But the resistance to longitudinal deformation of the panels is high, which makes it possible to use them to strengthen load-bearing structures.
Density. From 1200 to 1400 kg / m 3. Values vary due to possible fluctuations in humidity.
Vapor permeability. It is about 0.03 mg/(m·h·Pa). The presence of a porous structure does not prevent vapor exchange.
Humidity level. Within 9%. If the manufacturing technology is fully observed, then with constant exposure to water during the day, the indicator changes by less than 2 times.
Thermal conductivity. Coefficient - 0.26 W / (m K). If you sheathe a house with such material, then its energy efficiency will increase.

Extended table of general characteristics of cement-bonded particle boards

Sheet size:

width - 120 and 125 cm (standard);
length - 320 and 360 cm;
thickness - from 6 to 36 mm;
weight is due to dimensions: a panel 1200 * 3200 * 36 will have a mass of 195 kg.

There are other parameters, regulatory documents allow you to produce parts of the required dimensions.

Design parameters of the best-selling DSP models

Since the material is environmentally friendly and moisture resistant, the area where it can be used is quite extensive:

Frame construction. In such a situation, dimensional parts should be used, because they reinforce the supporting structures. Wall ceilings are entirely sheathed with slabs, the field of which is processed.
Facade decoration. This is the best option if the climate is high humidity and severe frosts. The panels are used when installing a system with additional ventilation: they are laid on the crate. Due to the fact that the products are polished or unpolished, they are left unlined or plastered.
Internal work. Plates make wall and ceiling cladding. In larger processes, the material is used to equip the attic and subfloor.

Renowned brands such as Tamak offer a complete line of high quality cement boards for a variety of finishes and applications.

Characteristics allow the use of chipboard cement panels almost everywhere, if appropriate. Although all the work can be done with your own hands, the dimensions and weight of the parts require the presence of an assistant.

For comparison with other materials, we propose to use such characteristics as:

fire safety;
ease of installation;
resistance to mold and disease;
reviews of builders;
feedback from residents and homeowners.

Fire safety and flammability class

In this parameter, DSPs are superior not only to polymeric insulation and PVC, but even to wood concrete. TsSP is assigned a flammability class - G1, that is, they are slow-burning. Due to the large proportion of cement, each of the chips is surrounded by a cement stone, so to start the pyrolysis process in wood close to the surface exposure to a temperature of 500 or more degrees for half an hour is necessary.

As soon as the thermal effect is eliminated, the pyrolysis process is quickly completed, because close contact of many chips is necessary for the start of a self-sustaining reaction.

If the temperature exceeds 700 degrees, and this effect lasts more than an hour, then the pyrolysis of the chips begins throughout the entire depth of the plate.

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

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

Therefore, the DSP one of the safest in the fire plan of materials and is comparable to GKL 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 CSP much harder than most finishing materials.

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

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

Cutting the material is also difficult, because you need to use high-speed circular saw and diamond-coated blade 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 mass of any other finishing material, including LSU and wood concrete.

Resistant to mold and disease

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

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