Glue for aerated concrete blocks: types, characteristics and use. Composition, glue properties and calculation of consumption per 1 cubic meter. m.

Aerated concrete blocks are becoming more and more common in construction because of their superior insulation qualities and lightweight nature. However, using the proper kind of adhesive is essential to guaranteeing the longevity and structural integrity of buildings built with these blocks. Strong, long-lasting bonds between the blocks must be created using glue made especially for aerated concrete blocks if you want your building project to last.

For aerated concrete blocks, there are several glue options available, each with special qualities fit for distinct building requirements. Among the popular varieties are dry mix adhesive, polyurethane adhesive, and cement-based adhesive. Knowing the distinctions between these kinds will enable you to select the one that will work best for your project and provide the best usability and performance.

A combination of cement, fine sand, and chemical additives is usually used to make the glue for aerated concrete blocks. Together, these components offer outstanding durability, resistance to temperature changes, and bonding strength. The proper glue not only keeps the blocks together but also closes gaps and fissures, improving the structure’s overall stability and thermal efficiency.

It’s crucial to determine how much glue is appropriate for your project before using it on aerated concrete blocks. About 20 to 25 kg are used on average per cubic meter of aerated concrete. Depending on variables like the glue type and thickness of the adhesive layer, this computation may change. In order to reduce waste and guarantee a seamless, effective building process, accurate measurement and application are essential.

In any building project, selecting the appropriate glue for your aerated concrete blocks is essential. You can make sure that your building is durable and strong by being aware of the types, qualities, and appropriate application techniques. Having the appropriate knowledge regarding glue for aerated concrete blocks will help you meet your building goals with the greatest outcomes, regardless of whether you are an expert builder or a do-it-yourself enthusiast.

What glue is needed for aerated concrete

Why is the masonry solution’s less expensive version unavailable to you? What are the requirements for laying aerated concrete blocks in special compounds? Expert builders identify several justifications for using this composition.

Among them are the following:

  1. To decorate the correct masonry, it is necessary to provide a seam whose thickness should not exceed 10 mm subject to strict geometry of products. With the help of sand, cement cannot be created less than the declared parameters.
  2. Beginner installers prefer to save on the acquisition of consumables. In their opinion, such a working solution will cost much cheaper and will make the suitable size for seams.
  3. In fact, everything consists not only in saving financial resources. Such substances are not able to provide the level of strength that is required for aerated concrete material.
  4. The composition has a good level of thermal conductivity. Thanks to it, it is possible to create a strong connection that prevents the penetration of drafts inside the closed space.

A specific brand of cement is used as the active ingredient in a special glow for aerated concrete blocks, and the filler is composed of unique additives and plasticizers that give the structure a dense appearance.

The structure of cellular concrete is porous. When the standard composition is used, moisture particles will be quickly absorbed by the surface. Large pores in the building material cause the adhesive mass to become dehydrated, which is against the active component ratio.

It is brittle due to the fold, and the dynamic load has the potential to destroy it. The surface of aerated concrete blocks doesn’t require extra priming before installation begins.

Portland cement serves as the connecting element in the formulation of special glue. This kind of construction material has excellent performance qualities that offer durability and dependability over an extended period of time. Furthermore, this brand promises quick drying time following application.

  1. Concrete with a porous structure needs the right choice of consumable components that can provide the desired level of adhesion for further decoration.
  2. As a result, the process of plastering of such a surface differs in a mass of features.
  3. Decorative material evenly fills small defects and chips on the plane of the wall.

Producers of the aerated concrete block masonry solution incorporate unique polymer constituents that offer superior adhesion markers. With independent drying, this kind of auxiliary component can create an adhesive mass that doesn’t give a significant amount of shrinkage.

The overestimated cost of these compositions is their only drawback. The cost of the working composition will be significantly lower when conventional components are used, but it’s crucial to take into account the high consumption and operational characteristics of this combination.

Types of glue for aerated concrete

Aerated concrete block glue comprises polymer-based modifying additives in its composition. A specific brand of Portland cement serves as the mixture’s active ingredient. Every manufacturer uses a different manufacturing technology for their masonry composition, which has unique characteristics.

Experts identify several favorable attributes in these products, including the following:

  • High -quality connecting component;
  • The presence of quartz sand. It provides a high level of adhesion;
  • A large set of mineral and synthetic components that improve the technical features of the glue composition.

Products made as dry components are available for purchase. You can follow the directions on the package to prepare the necessary amount of the pantry solution.

Gas silicate block glue comes in large bags weighing anywhere between 20 and 50 kg. Water can be used to create a thick mass that guarantees the application of the thin layer. Every brand dries at a different rate.

Likewise, there are two types of glue for gas silicate blocks. He is capable of:

  • Thin -layer;
  • Thick -layer.

For seams, which should have a maximum thickness of 5 mm, the first view is advised. These kinds of compositions favor using premium aerated concrete components.

Their uniform structure and perfect geometry define them. I will have to modify the panting solution in this instance. The minimum adhesive mass volume is recorded while the work is being done.

Thick -concrete adhesive for aerated concrete

Thick-layer consumables are regarded as universally applicable. It is advised that they work with finishing material, which has a surface rife with errors and size irregularities. The technical characteristics indicate that the adhesive layer must have a minimum thickness of 10 mm.

The composition of the masonry is further separated into a number of other categories based on the circumstances of the working process.


These mixes fall into the category of exterior works where the temperature range is higher than five degrees. One benefit of this type of glue is that it can be used with white cement. The location is nearly invisible after the location;

They can be chosen for installation work in temperatures ranging from minus 15 to plus 20. Construction products are packaged with technical specifications displayed.

Prior to selecting the masonry composition, consideration must be given to the installation conditions, the moisture content, and the technical specifications of the gas-dilocate blocks.
