If a warm mortar for laying ceramic blocks is laid in a typical project, you should not replace it with a cement-sand mortar! Warm mortar for laying bricks in winter conditions Warm mortar with your own hands

Excellence in any industry is achieved by searching, trial, error, development, checking compound formulas, choosing the right solutions. The appearance on the market of one building material entails the arrival of the optimal option for the best layout.

With the advent of hollow ceramic blocks in construction, the best mixtures for their installation were developed. To date, there are mixtures with different names from different manufacturers, which are designed to connect ceramic blocks and foam materials similar in porosity.

Efficient 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 with sand, but special mixtures containing material with low thermal conductivity (perlite, vermiculite, pumice) and all kinds of plasticizers. The creation of a productive warm mortar for laying ceramic blocks is carried out on the basis of developments and practical tests, evaluations of performance, efficiency and compliance with the required indicators. Developers, technologists of many industrial enterprises for the production of technological mixtures are working on this.

Special composition

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

An increase in plasticity, frost resistance, water resistance, hardening is achieved by including additives with a polymer base. Porous fillers reduce thermal conductivity. Most customers buy the finished dry mix from various manufacturers, guided by reviews from other consumers and recommendations from experienced builders. Some consumers make the mixture themselves from the necessary ingredients. For this, components are bought in the right amount and mixed together.

Solution preparation

The mixture is prepared by adding to the composition the specified amount of ordinary, 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 must be diluted with 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 granulated bryla with increased whipping. Therefore, when a homogeneous mass is obtained, the mixing process is interrupted. A warm mortar for laying ceramic blocks is used for ceramic blocks, as well as in the construction of houses from aerated concrete and cellular foam concrete.

Significant advantages of a warm mortar for laying ceramic blocks

During construction, it is necessary to adhere to those components that are indicated in the approved project. In this case, a comparison with food products would be appropriate. A cake made with the addition of butter, vegetable fat, margarine will differ in its taste properties. So a house made of ceramics using a warm mortar will be better than the same building on a cement mortar. Benefits of using a warm solution:

high-quality connection of blocks without the manifestation of "cold bridges";
increase in energy efficiency (by 30% or more);
high strength;
long service life;
environmental friendliness and safety for health;
economy associated with the use of thin-seam masonry technology;
high level of moisture retention;
affordable cost.

Although the warm mortar for laying ceramic blocks is more expensive than ordinary cement and sand, its use guarantees the high quality of the constructed buildings. For a specialist, this will be visible immediately, and for a consumer it will manifest itself during the operation of the building.

Conclusion

In order to get a comfortable building, laid out of porous ceramics, aerated concrete, foam concrete, it is necessary to observe the manufacturability of processes and adhere to the guidelines for the use of materials. If experts say that ceramic blocks are best connected with a special warm masonry mortar, then this has significant practical and economic value.

In order for the design to turn out to be truly high-quality and reliable, the masonry mortar must have low thermal conductivity.

Warm mix" Perel", produced by TD Perel LLC, has excellent properties and unsurpassed quality. The low thermal conductivity of this mixture is achieved due to the inclusion of perlite sand in the composition. In addition, unlike standard mixtures, warm mortar " Perel also has a low density.

Heat-insulating masonry mix "Perel" - the choice of the majority

Before you start working with our solution, you need to carry out preparatory work:

cleaning masonry material from dirt and dust;
checking the strength and evenness of the base;
preparation of masonry mixture.

To prepare a heat-insulating masonry mortar, it is necessary to mix the product with water in the appropriate proportion (for 10 liters of water - 25 kg of dry mix). As a result of mixing, a homogeneous rigid-plastic consistency should be obtained. It is important to ensure that the resulting solution is protected from impurities, humidity and temperature extremes.

Advantages of "Perel" heat-insulating masonry mixtures:

impeccable quality;
increased thermal insulation;
lack of drying;
low density;
sound absorption;
fire retardant properties;
decorative qualities;
low price.

Using Blends" Perel"- the key to a strong, reliable and warm wall.

In recent years, many new types of wall materials have appeared that have high thermal insulation. However, the desired effect is not complete when using a traditional cement-based masonry mortar. The resulting seams do not have good thermal insulation, it is through them that the buildings are cooled and the cost of heating them increases. Also, conventional solutions can cause mold to form on wall surfaces.

Heat-insulating masonry mortar will help to solve the problem. Special compositions help to maintain the thermal parameters of the wall and reduce the heat loss of joints between bricks or large blocks. In their manufacture, porous materials are used, one of which may be perlite.

Features of heat-insulating masonry mixtures

Thanks to the heat-insulating mixture, it is possible to obtain a homogeneous masonry. They have a special composition that allows you to get a plastic and durable material with high strength. The heat-insulating masonry mixture prevents the formation of cold bridges. Thanks to it, good vapor permeability is ensured. Some manufacturers of ceramic blocks and other thermal insulation materials recommend using warm mixes for their masonry.

When choosing a heat-insulating mixture, it is necessary to take into account the following parameters:

density;
frost resistance;
compressive strength;
coefficient of thermal conductivity;
use temperature.

Due to the solidification of the porous material, the density decreases and the thermal protection of the material increases. The voids in it, which prevent heat loss, are created through the use of special substances in the composition - expanded clay, perlite, pumice or vermiculite. When preparing the mixture at the construction site, obtain a uniform distribution of the heat-insulating filler. This means that a high-quality composition can be made exclusively in the factory with careful adherence to technology.

The warm solution should have the following characteristics:

plastic;
high thermal insulation;
sound absorption;
good adhesion;
decorative attraction;
low density;
high-quality seam filling.

Preparation of heat-insulating mixture

The composition should be poured into a tank with warm water (25 kilograms of the mixture requires about 10 liters of water). After that, it is mixed until a homogeneous mixture is formed. The solution should stand for up to 5 minutes, then it is mixed again for several minutes. It should have a creamy consistency. Third-party substances or additives must not be introduced into the masonry mixture.

The Slavdom company offers to purchase heat-insulating masonry mixtures from such manufacturers as RAUF Therme, Porotherm, PEREL and OSNOVIT. They are delivered to all cities of the Russian Federation. You can get to know the products better in one of our offices, which are located in Moscow and St. Petersburg. Contact us!

Conclusion

With the advent of new building materials, corresponding terms are also formed, such as, for example, warm masonry mortar. Previously, it was understood in a literal sense: the usual building mix of cement and sand, but heated to work in cold conditions to ensure the quality of the brick wall. But then ceramic blocks appeared with many pores, which increase the thermal insulation properties of the structure, and the former composition becomes a weak link: the seams are a kind of cold bridges, that is, heat leaks through them.

This circumstance led builders to create mixtures of specially selected components that provide high thermal insulation of joint fillers. Porous minerals and products became such elements of the solution:

pumice, expanded clay and slag sands;
expanded perlite and vermiculite;
foam glass and asbestos-containing substances.

This made it possible to increase the heat resistance of the seams by 18%. Solutions are used on such bulk materials in the construction of structures made of foam concrete, porous ceramic blocks, cellular glass, glass pore and gas silicate concrete blocks.

Properties and compositions

Air is a poor conductor of heat, it is this quality that has allowed cellular products to become the basis of heat saving technologies. When erecting structures from macroporous building materials and laying wall elements, it is necessary to use solutions with light aggregates - this is perlite or pumice sand. Traditional masonry mass has a density of 1.8 t / m³, while wall blocks are much lighter - 0.5 t / m³. A regularity was revealed that with an increase in the specific gravity of a substance by 100 kg/m³, heat leakage increases by 1%.

The ideal solution would be to achieve a mass density at the level of the weight of the building blocks - 0.5. Such a mixture must also be workable and plastic, have high adhesion (sticking to the surface) and water-retaining properties to ensure the viability of the solution. It is possible to achieve a combination of such parameters by including special additives in the mortar mass - modifiers that improve the properties of the composition. Thus, a warm masonry mixture should consist of the following components:

cement;
porous sand powder;
modifying additives.

Light fillers are selected based on the capabilities of the local mineral mining base. The ratios of cement-sand are the same as for traditional mortars, depending on the required strength. It can be proportions 1:3 (M 75), 1:4 (M 50) and 1:5 (M 25). The last two dosages are used for low-rise construction of houses with walls made of highly porous blocks.

Reaching the minimum density

An additional possibility of saturating the solution with air and thereby reducing its weight is the use of turbulent mixers when mixing the masonry composition. At the same stage, air-entraining additives also give a good effect. Porogenerators have also been developed and are operating, which saturate the solution with air pores when it is stirred.

In some cases, expanded polystyrene granules can be used as a filler, which have practically no weight and very well saturate the mass with air. For plasticity, lime can also be added there. With the complex use of all methods of lowering the density - porous fillers, air-entraining additives, turbulent rotation, polymer additives - good results are achieved. This allows you to significantly limit heat leakage into the atmosphere through the building envelope, reduce their weight and reduce the consumption of mineral resources.

Making a mixture

Warm mortar for masonry is usually used in the construction of external walls, and in the construction of internal partitions - traditional plaster. Large construction companies bring to the site a ready-to-use mortar or a dry mixture is pumped into a supply silo to create when adding water directly at the construction site. But there is nothing complicated in preparing the solution: you can use ready-made dry powders, a large selection of which is presented on the construction markets, or choose the components of the mixture yourself and make it yourself. Tools and materials for work:

mixer - container or mechanism;
bucket, shovel and sieve;
water, sand, cement and additives.

Mixing proportions depend on the number of storeys of the building, in private construction it is 1:4 or 1:5, where 1 part is cement. Sequence of operations:

Clean the sand from debris and large inclusions by sifting through a sieve.
In a given proportion, pour cement and sand into the mixer, stir the dry mixture (3 minutes). Add some water to wet and stir for 2 minutes.
Add the liquid to the desired consistency, stirring for the same amount of time.
Pour the prepared solution into a storage container.

Masonry should be completed within two hours so that the mortar mass does not thicken. Preparing masonry adhesive from the factory mixture is even easier - just follow the instructions on the package.

Buy a ready mix or components?

The rather high price set for a warm dry mix encourages an amateur builder to ask such a question. It is clear that the main component in the price of any product is raw materials, and therefore it is necessary to approach the answer to the question from this position. So, a manufacturer of mixed products buys materials at wholesale prices much lower than market prices, and even uses its own raw materials, so for him the cost of components will in any case be lower than for a retail buyer who decides to make a mix in a handicraft way.

The thermal insulation dry mix has specific components that you will also have to look for before purchasing, and their price will not be low. So in terms of saving money from making your own hands, there are no prospects. In addition, in terms of the quality of the mixture, it must be taken into account that the factory conditions have a number of advantages:

The dosages of the components are worked out in the laboratory and carried out automatically on the production line. The consumer only needs to add water in the amount specified in the attached instructions.
To prepare the mixture, no special equipment is required (the same concrete mixer), the required amount can also be mixed in a small bowl using a household electric drill.
Factory mixtures include quality-improving additives and additives.
The range of powders produced by manufacturers, as a rule, provides for various subspecies for various application conditions - high humidity or low temperature, accelerated setting, etc.

With a large selection of mixtures, there is the same high probability of buying a fake under famous brands. Therefore, in order to make a high-quality warm mortar, it is necessary to purchase dry mixed powders in large specialized stores that receive products directly from manufacturers of masonry compounds.
