For laying aerated concrete blocks, a mounting adhesive specially developed for this purpose is used. It allows you to stack the products as tightly as possible to each other, so that the building receives increased thermal insulation qualities. After all, these products are used not only for construction, but also for the insulation of buildings and structures for various purposes. Mixtures for aerated concrete blocks must have high adhesive and thermal insulation qualities. They are made on the basis of polymer additives, cement, as well as sand and mineral fillers. Each ingredient performs its functions, providing plasticity, resistance to moisture, as well as an increase in strength characteristics. It is these qualities that the composition that you will use in the process of work should have.
Reviews on the advantages of glue for aerated concrete blocks over analog options
Glue for gas blocks has certain advantages, which is true when compared with analog compounds that have a different purpose. Thus, these mixtures are characterized by high plasticity,frost resistance, fairly fast setting, water-repellent characteristics, as well as an excellent degree of adhesion. According to users, due to the presence of Portland cement and high-quality sand in the composition, during the masonry process it is possible to make the thickness of the seams, which is equal to two millimeters. If we are talking about polyurethane adhesive, then it does not shrink during the drying process, which prevents the formation of cold bridges. After all, they are the reason that the walls let heat out.
As emphasized by the home craftsmen who were laying the described products, the glue for gas blocks is very convenient to use, to prepare it, it is enough to mix the dry concentrate with the liquid, the proportion recommended by the manufacturer should be taken into account. Despite the rapid setting, the solution remains viable for several hours after mixing. Consumers choose these formulations because they are 95% moisture resistant, have a fifteen-minute curing time, and can be adjusted within three minutes of being put in place. Internal fillers have a grain size of 0.67 mm, and you can work with these mixtures at a wide temperature range - from +5 to +25 degrees Celsius.
Reviews on frost-resistant adhesives for aerated concrete
Glue for gas blocks may have increased frost-resistant characteristics. According to buyers, these compositions should differ in certain features. In spite ofthe fact that antifreeze additives are included in the composition, it is not recommended to use winter glue if the temperature drops below -10 degrees Celsius. Adhesive for gas blocks of increased frost resistance, according to users, should have a gray color, environmental friendliness, resistance to aggressive natural influences, the ability to use both indoors and outdoors. In this case, the mixture should be characterized by low heat losses, as well as the ability to prevent the appearance of cold bridges.
Reviews on products from different manufacturers
If you want to use glue for gas blocks for work, it is recommended to read reviews about it. As users emphasize, the Kreps mixture has an optimal composition and high performance. This product can be used both indoors and outdoors, and features efficiency and economy among its features.
It is important to pay attention to the technical characteristics before purchasing, among them - the maximum grain size of the filler, which can reach a parameter of 0.6 mm; as well as the thickness of the layer, in this case it is equal to 3 millimeters. As practice shows and the masters say, the exposure time is equivalent to 10 minutes, the block can be corrected during the same period. Complete drying will occur after 4 hours. You should take into account the average consumption, this will save money that could be spent on the purchase of unclaimed adhesive packages. 1 cubic meter will take about 25kilograms of composition.
Reviews about the glue "Azolit"
No less effective for winter construction is the Azolit composition, which has water-repellent characteristics and is intended for laying not only aerated concrete, but also silicate, as well as foam concrete products. Consumers claim that the average consumption per 1 cubic meter is 25 kilograms, the mobility of the adhesive is maintained for a maximum of 7 minutes, the bending strength is 4.1 MPa. Complete drying should be expected 2 hours after mixing, and the moisture content by weight is 0.08%. Quite often, specialists are interested in such a parameter as compressive strength, in the case of the Azolit composition, it is equivalent to 11.2 kgf / m². Moisture absorption by weight is 2 percent, but adhesion to a concrete base is 0.4 MPa.
Axton glue reviews
Glue for gas blocks Axton today is popular among consumers, it is a dry mix, which is designed to prepare a solution. This composition can be used for outdoor work, where not only gas blocks are involved, but also bricks, as well as any other products. Users like that this adhesive is able to withstand temperatures in a fairly wide range - from -50 to +50 degrees Celsius. Among other things, the products are distinguished by ease of preparation, high strength of the joints formed, accurate dosage of components, as well as low consumption of the mixture during work.
The described adhesive for laying the gas block is made in Russia, so its cost is negligible and amounts to 185 rubles. for a 25 kg bag. Drying should be expected after 24 hours minimum, while the maximum limit is 48 hours. Adhesion is 0.4 MPa. According to users, the thickness of the seam can vary from 2 to 5 millimeters, this allows you to level the unevenness of the blocks. The composition can be stored for 120 minutes, and to correct individual blocks after laying - within 10 minutes.
Quality characteristics of Axton glue
If you decide to use Axton gas block adhesive (25 kg), you should know that the mentioned volume will be enough for 1.22 cubic meters. The composition is presented for sale in the form of a gray powder, which can be used after mixing when laying blocks that have grooves or lack them.
Using Axton glue
According to experienced users, to work with this adhesive, it is necessary to prepare a notched trowel, trowel or steel trowel. Application to the surface is carried out in the most even layer, which can be leveled using a serrated working surface. As soon as the adhesive for Axton gas blocks, reviews of which will help you make a choice, has been applied to the base, you can lay the product, the position of which is leveled with a hammer. Excess mixture must be removed with a trowel.
Reviews recommend cooking this amounta composition that you will be able to develop in a short time, otherwise the solution will lose its elasticity, and you will face an overrun of the material. It is important to prepare hot water for mixing, the temperature of which is 60 degrees.
Conclusion
Glue for Axton gas blocks (25 kg), reviews of which are positive, should be applied to a pre-prepared surface, which must be dedusted. To do this, the base is cleaned with a soft brush. It is also necessary to ensure that there are no greasy spots on the surface of the products, otherwise the base must be degreased.
