Working with aerated concrete blocks is a pleasure. It is not without its drawbacks, however, with its help it is possible to complete the indicated 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 overflowing with construction raw materials of various types, and in order not to make common mistakes in the selection process, you should give preference to products of reliable brands. 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 is composed of lime or cement. The raw material is called honeycomb because of its structure, and has a low weight.
The technology is improving every year, and raw materials are becoming 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 type of porous concrete, which, in fact, is a subspecies of artificial stone. It contains a number of cells. For manufacturing, a gasifier, cement and quartz sand are used. Gypsum, ash or lime can also be added. After prolonged exposure to temperature and high pressure, a number of chemical reactions take place, which contribute to the formation of pores.
When choosing gas blocks, you should pay attention to the following selection criteria:
Aerated concrete is autoclaved cellular blocks. The components used are thoroughly mixed, after which they undergo long-term heat treatment at the factory.
What are:
Best 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 construction devices. 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. It can be used to create unusual arches, partitions and other decorative elements. When building walls, such elements are simply irreplaceable. |
Strength index | Despite its insignificant weight, this characteristic is amazing. Such a building element is considered an excellent compromise between thermal insulation, weight and strength. Depending on the brand purchased, the compression ratio will be 1.5-3.5 kgf / cm2. |
Sound insulation 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 with a low thermal conductivity coefficient. For self-supporting structures, this is extremely important, as the developer is guaranteed to receive excellent thermal protection during the colder months of the year. However, compliance with the exact geometry, in this case, is mandatory. Throughout the summer, the premises will be kept at the optimum temperature, without the risk of significant heating due to sunlight. |
Weight | The dimensions of the standard block will be 62.5x10x25 cm. The weight of the product is 8 kg. Density coefficient 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 are classified as non-combustible, therefore they have the highest fire resistance class. Structures, fences and other types of buildings erected from aerated concrete belong to the I and II class of fire safety. |
Resistance to environmental factors | Bacteria and other harmful organisms will not grow 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 the raw materials do not need additional (protective) impregnations, unlike wood and other expensive building materials. The moisture resistance indicator is excellent. |
Sustainability | In order to measure the level of radioactivity of individual components, you will need a special laboratory and a whole staff of qualified personnel. It is impossible to calculate this indicator in the field. It was experimentally revealed that the radioactivity of aerated concrete blocks is within normal limits. No toxic components are used in the manufacturing process, so it can be compared with the characteristics inherent in natural materials. |
How to choose a quality and inexpensive building material? To do this, you have to get acquainted with their varieties and basic characteristics. In the process of aerated concrete production, various binders can be used, including those of mineral origin. 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. Waste from thermal power plants (ash) or quartz sand can also act as a filler. Waste from various technological processes, beneficiated ore or ferroalloys can also be used.
The rating of high-quality gas blocks opens a budget product from a Danish company that has Scandinavian roots. Their production of building materials was established back in 1979. The company has many subsidiaries, and in 2009 one of the production facilities was established in Russia.

In the process of laying aerated concrete blocks, it is necessary to take into account such indicators as the length of horizontal seams, which should not exceed 0.8 cm. 0.3 cm is the maximum available vertical seam. 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.
The quality of the wall will largely depend on the level of masonry in 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 effort should be made to eliminate it.
In the process of working with aerated concrete blocks, only specialized fasteners are used. Regular self-tapping screws will not hold on to the elements as tightly and securely.
The consumption of glue will increase if the blocks have handles or other protruding elements. The technology used involves filling absolutely all cavities during the manipulation process. It is better to entrust transportation to professionals, as their surface is easily damaged. It will not be superfluous to cover the blocks with polyethylene for a while. Thus, you can protect them from negative external factors.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.
