Features of the use of ceramic blocks. Warm solution: features, composition and recommendations Warm solution or regular

Excellence in any industry is achieved through search, trial, error, development, testing of compound formulas, selection right decisions. The appearance of one building material on the market leads to the arrival optimal option for the best layout.

With the advent of hollow ceramic blocks in construction, best mixtures for their installation. Today there are mixtures with different names various manufacturers, which are intended for connecting blocks of ceramics and foam materials of a similar porosity structure.

Effective mixture for hot ceramics

In order to minimize heat loss penetrating through the seams when laying porous blocks, it is recommended to use not the usual solution of cement and sand, but special mixtures containing material with low thermal conductivity (perlite, vermiculite, pumice) and all kinds of plasticizers. The creation of a productive warm solution for laying ceramic blocks is carried out on the basis of development and practical testing, assessments of productivity, efficiency and compliance with the required indicators. Developers and technologists are working on this manufacturing enterprises for the production of technological mixtures.

Special composition

Each manufacturer produces a mixture based on its own standards, developed by specialists. All mixtures are sold in dry form. In a packaging unit (bag weighing 20-35 kg) collected required amount mixture, which will guarantee the highest quality of the finished solution. 35 kg of dry mixture yields 31 kg of mortar for laying ceramics. As in sand- cement mortar, the primary binding component in it is Portland cement.

Increased plasticity, frost resistance, water resistance, and acceleration of hardening are achieved through the inclusion of additives with a polymer base. Porous fillers reduce thermal conductivity. Most customers buy the finished version of the dry mixture from various manufacturers, guided by reviews of other consumers and recommendations experienced builders. Some consumers make the mixture themselves from the necessary ingredients. For this purpose, components are purchased in the right quantity and mix with each other.

Preparation of the solution

Prepare the mixture by adding the specified amount of regular, preferably tap water, at the construction site. Spring and well water may contain various minerals that will cause adverse reactions. Although the solution is called warm, this does not mean that it needs to be diluted hot water. Mixing is carried out in a concrete mixer. It is not recommended to stir the mixture for a long time, since perlite turns into granular fluff when vigorously whipped. Therefore, when a homogeneous mass is obtained, the mixing process is interrupted. Warm mortar for laying ceramic blocks is used for ceramic blocks, as well as in the construction of houses made of aerated concrete and cellular foam concrete.

Significant advantages of warm mortar for laying ceramic blocks

During construction, you must adhere to those components that are indicated in the approved project. In this case, a comparison with food products. Cake made with butter, vegetable fat, margarine will differ in its taste properties. Likewise, a house made of ceramics using warm mortar will be better than the same structure using cement mortar. Advantages of using a warm solution:

high-quality connection of blocks without the appearance of “cold bridges”;

increase in energy efficiency (by 30% or more);

high strength;

long service life;

environmental friendliness and health safety;

cost-effectiveness associated with the use of thin-seam masonry technology;

high level of moisture retention;

affordable price.

Although warm mortar for laying ceramic blocks is higher in cost than conventional cement and sand, its use guarantees high quality of constructed buildings. For a specialist this will be immediately visible, but for the consumer it will appear during the operation of the building.

Conclusion

In order to create a comfortable building made of porous ceramics, aerated concrete, foam concrete, it is necessary to observe the manufacturability of the processes and adhere to the instructions for the use of materials. If experts say that it is best to join ceramic blocks with a special warm masonry mortar, this means there is significant practical and economic value in this.

Thermal insulating heat-saving masonry mortar

But, the use of glue for filling joints when laying single-layer walls made of ceramic, expanded clay concrete, wood concrete blocks, and blocks of other materials is only possible when using blocks with height deviation of no more than +/- 1 mm. (category 1 for deviation of geometric parameters).

Not all manufacturers produce such blocks. Yes and blocks with a height deviation of no more than +/- 3 are more affordable at a price mm. (category 2). These blocks must be placed in the wall on a mortar with a joint thickness of 8-12 mm.

Application of conventional cement-sand mortar for laying external single-layer walls made of blocks significantly reduces their heat-shielding properties. The thermal conductivity coefficient of masonry increases to 30% compared to masonry with glue (for D400-500 blocks). It's too much.

That's why, for laying external single-layer walls made of blocks, heat-insulating lightweight warm mortars with a dry density of less than 1500 should be used kg/m3.

How to properly prepare thermal insulating masonry mortar

Warm light masonry mortar prepared using cement and lightweight aggregates - expanded clay or perlite sand, polystyrene foam granules.

Perlite is rock volcanic origin, frozen stone foam.

D adding lime to the mixture increases the plasticity of the solution.

Warm light masonry mortar is convenient to prepare fromdry masonry mixture. On construction market you can find ready-made dry mixes different composition for the preparation of heat-insulating masonry mortar.

For example, a dry masonry mixture from one of the manufacturers based on cement, mineral filler - perlite and plasticizing additives has the following characteristics:

Name of the mixture - Dry masonry heat-insulating mixture.
Compressive strength grade: M50.
Coefficient of thermal conductivity ( W/m°C) — 0,21 / 0,93
Average density ( kg/m 3) — 1000 / 1800
Output of solution from 20 kg. dry mixture - 34 l.
Frost resistance - 25 cycles
Shelf life: 12 months.

(The value for ordinary cement-sand mortar is indicated through a slash (/).

From the given data it is clear that more than 4 times more heat is lost through a seam made from a regular mortar than through a seam made from a heat-insulating mortar.

The method for preparing the solution is usually indicated on the packaging of the finished dry mixture. Exact implementation of the recommendations indicated on the packaging guarantees a solution with good plasticity and adhesion to masonry blocks.

When choosing a ready-made dry mixture, you should be guided not only by price, but also take into account how much of the finished solution is obtained from one package. For example, a 25-kilogram bag of dry mixture from one manufacturer produces 40 liters of ready-made solution, but a package of the same weight from another manufacturer will allow you to prepare only 18 liters of solution.

The amount of ready-made solution that can be prepared from the dry mixture must be indicated on the product packaging.

When purchasing a dry mixture, also pay attention to the thermal conductivity coefficient - the lower, the better.

Composition of lightweight cement mortar for laying blocks

For self-cooking warm light masonry mortar grade M50, the table gives several recipes:

note — the dosage of binders, fillers and additives must be made by weight.

To improve the plasticity of the solution, hydrophobic or air-entraining additives are used in amounts up to 0.2% by weight of cement.

As the density of the solution decreases, the thermal conductivity coefficient also decreases.

When preparing the solution, 50-70% water, aggregate and cement are first loaded into the container, which are mixed for 1-2 minutes. After this, the composition is mixed with the rest of the water and additives.

Perlite grains are very fragile. When mixed for a long time in a concrete mixer, they are crushed, which reduces the heat-saving properties of the solution. Do not mix the solution with perlite longer than necessary.

When laying, the block is lowered onto the mortar from above, avoiding horizontal movement of more than 5 mm. Excess solution that is squeezed out is removed immediately, preventing it from setting. Blocks can be straightened by rocking or tamping with a tool to prevent mechanical damage.

It is recommended to moisten the block surfaces with water before applying the solution.

In progress masonry work It is necessary to provide protection for masonry joints from too rapid drying and atmospheric influences - sun, rain, frost.

Consumption of mortar for laying blocks

For masonry 1 m 2 single-layer wall from smooth blocks 30 - 40 thick cm. approximately 20 - 30 liters of solution are needed with a seam thickness of 10-12 mm.

For buildings 1-2 floors high You can further reduce heat loss through the mortar joint, as well as reduce its consumption. To do this, when laying the mortar, apply it in two stripes along the outer and inner surface walls, leaving an air gap in the middle of the wall in a seam 1/3 - 1/4 wide of the block width. This measure reduces the thermal conductivity of the seam, but at the same time reduces bearing capacity masonry - therefore it is used only for buildings of small height.

A smaller amount of mortar will be needed if you use blocks with a tongue-and-groove connection of vertical joints for masonry. In this case, vertical seams are not filled with mortar.

The use of warm, lightweight masonry mortar can significantly improve the thermal conductivity of the wall compared to conventional mortar, but not so much as to be on par with an adhesive joint. In addition, the consumption of glue is several times less than that of a light solution, and the price of ready-made dry mixtures of glue and solution is almost the same.

THERMAL INSULATION MASONRY MIXTURES SOLUTIONS

Designed for stone and (or) brickwork with elevated thermal insulation properties. Recently, wall materials with increased thermal insulation properties have become widespread - hollow porous ceramic blocks, concrete blocks made of porous aggregates, large-format blocks made of cellular concrete.

The effect of using such materials increases if the thermal conductivity masonry mortar not inferior to the same indicator wall material. As is known, common cement-sand masonry mortars have poor thermal conductivity (0.8-0.9 W/m K), especially in comparison with ceramic porous blocks (0.16 W/m K) that they hold together, as a result With this design, cold bridges are formed at the seams. Research conducted at the Institute of Building Physics indicates that increasing the thickness of joints to 10 mm leads to a decrease in the average thermal resistance structures by approximately 20% due to the appearance of cold bridges. Therefore, it is very important when laying warm ceramics to use special warm masonry mortars. Basis for production thermal insulation masonry mixture There are two fillers: perlite and expanded clay.
