Working with aerated concrete blocks is a pleasure. It is not without flaws, but it can be used to complete the designated scope of work much faster. In addition, the walls erected with its help become warmer, which is extremely important during the ongoing financial crisis. However, such functionality is inherent only in high-quality raw materials, which are produced by the world's best manufacturers. The modern market is full of building materials of various types, and in order not to make common mistakes in the selection process, products of reliable brands should be preferred. We propose to talk about them in our article.

Aerated concrete is a category of building material, for the manufacture of which sand, cement and a number of reagents are used, which turn into foam in the process of interaction with cement. Often we are talking about a paste or powder made on the basis of aluminum. As a result of interaction with lime or cement, pores are formed. The bubbles are evenly distributed throughout the volume. Their shell consists of lime or cement. The raw material is called cellular because of its structure, and has a low weight.
Every year the technology improves, and raw materials become cheaper. This is due to the applied production technology and the cost of purchasing raw materials. Aerated concrete is a simple and, at the same time, inexpensive solution. Gas blocks are a kind of porous concrete, which, in fact, is a subspecies of artificial stone. It contains a number of cells. For the manufacture of used blowing agent, cement and quartz sand. Gypsum, ash or lime may also be added. After prolonged exposure to temperature and high pressure, a series of chemical reactions occur, which contribute to the formation of pores.
When choosing gas blocks, you should pay attention to the following selection criteria:
Aerated concrete are cellular autoclaved blocks. The components used are thoroughly mixed, after which they undergo a long heat treatment at the factory.
What are:
The nicest properties | Description |
---|---|
Ease of processing | This advantage is considered undeniable. You can saw, cut and give an unusual shape to the blocks yourself, using improvised building tools. Largely due to the production technology used, the material is often used in the construction of various kinds of objects, both residential and non-residential, as well as in the implementation of finishing work. The thermal conductivity of a dry block reaches 0.12 W / m ° C. With it, you can create unusual arches, partitions and other decorative elements. When building walls, such elements are simply irreplaceable. |
Strength index | Despite its low weight, this characteristic is amazing. Such a building element is considered an excellent compromise between thermal insulation, weight and strength. Depending on the brand being purchased, the compression ratio will be 1.5-3.5 kgf/cm2. |
Soundproof performance | The structure perfectly dampens extraneous noise. The degree of absorption depends on the brand used, the thickness of the walls being erected, the density of the mortar and the masonry technology. |
Thermal insulation properties | Blocks marked D500-600 are considered excellent thermal insulation materials, which have a low thermal conductivity. For self-supporting structures, this is extremely important, as it is guaranteed that the developer will receive excellent thermal protection during the cold months of the year.However, observance of exact geometry, in this case, is obligatory. During the summer, the rooms will be maintained at an optimal temperature, without the risk of significant heating due to sunlight. |
The weight | The dimensions of the standard block will be 62.5x10x25 cm. The weight of the product is 8 kg. Density factor 500 kg/m3. Thus, it will be possible not only to complete the construction in the shortest possible time, but also to save on mortar and other consumable components. |
fire resistance | Such raw materials belong to the category of non-combustible, therefore they have the highest class of fire resistance. Structures erected from aerated concrete, fences and other types of buildings belong to fire safety classes I and II. |
Resistance to environmental factors | Bacteria and other harmful organisms will not multiply in such material. For insects, such an environment is also considered unfavorable for life. Fungal spores cannot be detected even in the presence of high humidity in warm weather. It should be noted that raw materials do not need additional (protective) impregnations, unlike wood and other expensive building materials. The moisture resistance is excellent. |
Environmental friendliness | In order to measure the level of radioactivity of individual components, a special laboratory and a whole staff of qualified personnel will be needed. In the field, it is impossible to calculate this indicator. Empirically, it was found that the radioactivity of blocks of aerated concrete is within the normal range. No toxic components are used in the manufacturing process, so it can be compared with the characteristics inherent in natural materials. |
How to choose high-quality and inexpensive building material? To do this, you will have to familiarize yourself with their varieties and basic characteristics. In the production process of aerated concrete, various binders, including those of mineral origin, can be used. The type of additives is strictly established by GOST. Overview of the main types:
Such information is indicated by the manufacturer in the form of appropriate markings and in the name of the material. Also, waste from thermal power plants (ash) or quartz sand can act as a filler. Wastes from various technological processes, enriched ore or ferroalloys can also be used.
The rating of high-quality gas blocks opens the budget product of the Danish company, which has Scandinavian roots. They started producing building materials in 1979. The company has many subsidiaries, and in 2009 one of the production facilities was established in Russia. Size range: length 62.5 cm, height 25 cm, width can be 10, 15, 20, 25, 30, 37.5 cm.The comparison table looks like this:

In the process of laying blocks of aerated concrete, it is necessary to take into account such indicators as the length of horizontal joints, which should not exceed 0.8 cm. 0.3 cm is the maximum available vertical joint. Excess solution does not need to be rubbed or washed out; a special trowel is used for this.If you plan to carry out the installation yourself, then you should acquire scaffolding, without which it will not be possible to complete the construction. With such a device, it is not only convenient, but also safe to work with.
The quality of the wall will largely depend on the level of masonry of the first or starting row. That is why the masters of their craft recommend not to neglect the building level from the very beginning of the manipulations. Only with its help can you be sure that the row is laid out correctly. If any inconsistency or oversight is found, every possible effort should be made to eliminate it.
In the process of working with aerated concrete blocks, only specialized fasteners are used. Ordinary self-tapping screws will not hold in the elements as firmly and reliably.
Glue consumption will increase if the blocks have handles or other protruding elements. The technology used implies the filling of absolutely all cavities in the process of manipulation. It is better to entrust transportation to professionals, as their surface is easily damaged. It will not be superfluous for a while to cover the blocks with polyethylene. Thus, you can protect them from negative external influences. In the process of laying door and window openings, it is difficult to get into the length of the existing row. In this case, a hacksaw will come to the rescue, with which you can remove an extra piece of the part. Aerated concrete belongs to the category of pliable materials that are easy to process.
