Gas silicate blocks are one of the most popular building materials on the modern market. The houses built from them are characterized by durability, attractive appearance and excellent operational characteristics. But, of course, to build high-quality walls from such blocks is possible only with the right choice of fastening mixture. In the market today, there are several types of tools such as glue for gas silicate blocks. Consumption per 1m3 of these funds can vary significantly.
Mortar or glue?
Sometimes gas silicate blocks are simply laid on a cement-sand mixture. However, this method of walling is used only in extreme cases. The advantage of gas silicate blocks is primarily that they are able to perfectly retain heat indoors. By this indicator, such blocks are not inferior even to popular wood. The low thermal conductivity of the gas-silicate material is associated primarily with its porous structure.
When using ordinary cement mortar in a masonry from such blocks, bridges of cold subsequently arise . And this, in turn, reduces the main advantage of gas silicate to nothing.
When using adhesives, the building blocks of this variety are stacked according to a special technology. A fastening agent is applied to the rows and between the individual elements in a very thin layer. As a result, there are no cold bridges in the masonry. Sometimes such mixtures are applied with a rather thick layer. But in this case, special additives necessarily increase their heat-preserving qualities.
Modern adhesive for gas silicate blocks: consumption per 1m3
There are funds intended for laying gas silicate blocks, in most cases relatively inexpensive. But, of course, before buying such a composition, you should definitely make a calculation of its required quantity. Consumption for glues for gas silicate blocks of different grades can vary greatly. Some adhesives are applied in the masonry with a layer of 5-6 mm, others - 1-3 mm. The permissible thickness is usually indicated by the manufacturer on the packaging. Also in the instructions in most cases there is information about the estimated consumption per 1 m 3 of masonry.
To make all the necessary calculations, so if necessary it will be completely not difficult. In order to find out the right amount of mixture, you must first calculate the total volume of the masonry. To do this, you simply have to multiply the length, width and thickness of each wall, and then add the results.
In most cases, the glue consumption for gas silicate blocks according to manufacturers is 15-30 kg per 1 m 3 . That is, a master’s cubic meter of masonry should take about one bag of the mixture. However, unfortunately, manufacturers usually underestimate the cost of sales compounds a little. In fact, most often when laying on 1 m 3 it takes 1.5 bags of the mixture.
Characteristics of adhesives for gas silicate blocks
The basis of such compositions is often the same cement mixture. However, in the manufacture of adhesives of this kind, manufacturers usually add to them, in addition to standard components, special substances that increase their ductility, moisture resistance and frost resistance. Also, the solution for gas silicate blocks often includes additives designed to improve heat-preserving qualities.
Such agents are, in most cases, dry mixes packaged in bags. The preparation of glue from them is done simply by adding water in the right quantities.
Thus, ease of use is what distinguishes, among other things, glue for gas silicate blocks. Prices for such compositions are usually not too high and are quite comparable with the cost of a standard concrete mortar.
Types of adhesive for gas silicate blocks
All currently marketed compositions intended for masonry of this material are divided into several varieties:
adhesives used for the construction of partitions and walls inside the building;
compounds intended for masonry outside;
universal mixtures, which are allowed to be used both indoors and outdoors;
mixtures with increased pour point;
construction glue intended for the laying of enclosing structures of those buildings, which will subsequently be operated in conditions of high humidity.
Glue manufacturers
Of course, when choosing the most suitable composition for laying walls from gas silicate blocks of the composition, attention should be paid not only to its specific purpose, but also to the brand of the manufacturer. Today many companies supply similar mixtures to the domestic market. The most popular brands of adhesives among Russian developers are:
Unix compounds for aerated concrete
The laying of gas silicate blocks on glue of this brand can be carried out both indoors and outdoors. It is also allowed to use Unix for sealing chips in aerated concrete. Correct the position of the blocks when using this composition can be within 10-15 minutes. Consumers attribute the advantages of Unix glue, among other things, to the fact that it differs in heat-saving qualities almost as much as cellular concrete itself.
Also a plus of such mixtures is resistance to moisture and very low temperatures. According to the manufacturer, Unix Uniblock is an absolutely environmentally friendly product. The recommended layer of its application is 5-10 mm.
Another unconditional advantage of glues of this brand is their availability. Unix Uniblock, unlike mixtures of many other manufacturers, can be purchased at almost any building materials store.
The mixture "Founces Selform"
This summer glue is made on the basis of a cement-sand mixture. He also earned relatively good reviews from consumers. Among its undoubted advantages, among other things, include low cost with good performance. In order to give the glue the properties appropriate for aerated concrete masonry , the manufacturer adds special substances to it that increase its heat-preserving qualities.
The thickness of the masonry seam when using the "Founder Selform" mixture can be equal to 2 mm. The advantages of this glue include the fact that it is able to penetrate into the smallest recesses and irregularities of the blocks, which, in turn, increases the adhesion strength. There is another unconditional advantage of this adhesive for gas silicate blocks. Consumption per 1m3 of it is only about 25 kg.
Ytong facility
Glues of this brand are quite expensive. But they also have excellent characteristics. You can apply Ytong building glue to the blocks with a layer of only 1 mm. Therefore, its consumption is very small. The composition of mixtures of this brand, in addition to cement, includes polymers, mineral additives and special substances that give it plasticity. Consumers include the advantages of Ytong adhesives, including their ability to quickly set. Also, a high degree of frost resistance is considered an advantage of mixtures of this brand. You can use such adhesives, including when erecting building envelopes in the winter season.
Mixtures "Standard Teplit"
Like Unix, such formulations are found on sale quite often. The advantages of winter glue "Etalon Teplit" consumers include primarily a high degree of plasticity. Being applied to gas silicate, this composition does not delaminate and does not spread. You can store this glue after cooking without losing quality for several hours. Moreover, in the masonry, he grasps literally in 10-15 minutes.
Lower construction costs are also what this adhesive for gas silicate blocks is valued for. Consumption per 1m3 of it is only 25-30 kg.
Prestige funds
It is also a very high-quality mixture, which can be used both in the warm season and in the cold. The undoubted advantages of these compounds consumers include primarily a high degree of plasticity and reliability. Prestige glue preserves viability within 3 hours. It can be applied to blocks with a layer thickness of 3-6 mm. The grasped mixture reaches full strength in three days.
Adhesive for gas silicate blocks: prices for products from different manufacturers
The cost of compositions intended for the laying of gas silicate blocks may depend not only on the brand, but also on the supplier. The price of Unix glue is, for example, 240-260 rubles. per bag 25 kg. For the same amount of funds, “Founder Selform” will need to pay about 200-220 rubles. Glue Ytong costs about 310-330 rubles., And "Standard Teplit" - 170-200 rubles. For a bag of 25 kg "Prestige" will have to pay only 130-150 rubles.
