Currently on the market you can find many different materials suitable for the construction of buildings. Many people prefer aerated concrete. Let's talk about Ytong products.

Compound

Gas blocks of the German company Ytong consist of a special mixture, which includes several elements.

When they are mixed, a special porous structure of parts is formed. This is:

• quartz sand;
• Portland cement;
• aluminum powder and suspension;
• crushed lime (it can be slaked or quicklime);
• water (only approved by Gosstandart).

The basis of the gas block is quartz sand. Aluminum powders and suspensions also play an important role. They form alumina and hydrogen, which imparts porosity to the material. At the same time, experts say that all the characteristics that the material possesses will be the same for both vertical and horizontal installation of the structure.

Ytong aerated concrete blocks must be sent to special autoclave ovens, in which they are strongly compressed at a set level of moisture and temperature. After that, heavy-duty construction products are obtained that can withstand almost any chemical reaction.

Properties

Experts note that aerated concrete has a number of important properties. It is characterized by high strength, despite its relatively low weight (one square meter accounts for 0.5 tons of material). It is especially typical for models of smooth D500 blocks, as they have a higher density. Also, such blocks provide excellent thermal insulation, which is achieved due to the porous structure. As for the sizes, they are varied. On sale there are options 75x250x625, 625x250x100, 50x250x625, 100x250x625, 600x250x375, 300x250x625 mm, etc.

Another important property of Ytong aerated concrete is good fire resistance. This material contains special mineral substances that do not burn. The material is able to withstand severe frosts.

The Ytong gas block has excellent sound insulation properties. Due to the cellular surface, the blocks can significantly reduce unnecessary noise. Due to this, walls made of such material can reduce the penetration of sounds into the building.

An important property of Ytong aerated concrete is its seismic resistance . Therefore, buildings from these blocks can be built even in earthquake-prone areas. At the same time, the building material is lightweight and has a thin-seam inlay on special adhesives.

Another valuable property of gas blocks of this manufacturer is efficiency. Compared to standard masonry, the technique of thin seams is the cheapest, since in this case it is not necessary to work with an adhesive solution. This significantly reduces costs and saves time.

Aerated concrete of this brand is made from environmentally friendly, natural components. Therefore, it is absolutely harmless to human health. And the porous structure of each block provides air circulation and evaporation of excess moisture, which stops the formation of mold and mildew on the coating. Excellent vapor permeability allows you to create a favorable microclimate inside the building. However, it should be remembered that due to too strong porosity, aerated concrete in rooms with too high humidity levels can only be laid with special additional protection. Therefore, it is not suitable for all structures and premises.

It is also important not to forget that the material is fragile . Under strong mechanical stress, it can be destroyed. Also, blocks have a reduced level of compressive strength due to a too low thermal conductivity coefficient. Therefore, if the permissible value is exceeded, the structure may be damaged.

Varieties

Today, Ytong produces two types of gas blocks:

• smooth;
• tongue-and-groove.

Tongue-and-groove

Such blocks are used for external and internal decoration (for partitions, walls, lintels, ceilings, restoration work). With the help of a tongue-and-groove structure, you can easily connect all the parts to each other without using adhesives.

This type of material is u-shaped . It provides the tightest connection, as a result of which heat loss is significantly reduced. Often this variety is used as formwork during the manufacture of reinforced lintels and stiffeners.

The D400 model belongs to the tongue-and-groove blocks (its dimensions can be 375x250x625, 300x250x625 mm). As a rule, it is used to decorate external walls without insulation. The density of this variety is 400 kg / m3. The vapor permeability is 0.23, and the frost resistance is 35.

Also, aerated concrete with a groove-ridge includes samples D500 with dimensions 175x250x625, 200x250x625, 240x250x625, 250x250x625, 300x250x625, 375x250x625 mm. Their density is 500 kg / m3, frost resistance - 35. Vapor permeability is 0, 20.

Smooth

Such blocks, like the previous ones, can be used for a variety of purposes (exterior and interior decoration, construction of partitions, ceilings, stairs, walls). They have strict geometric shapes and a uniform surface. Also, this material often acts as a launching pad for laying finishing coatings, gluing wallpaper.

The smooth variety of Ytong aerated concrete includes D400 models , the size of which can be 150x250x625, 200x250x625, 240x250x625, 250x250x625, 300x250x625, 375x250x625, 400x250x625, 500x250x625 mm. The density of such building gas blocks reaches 400 kg / m3. Their technical characteristics are the same as those of the D400 material with a groove-ridge (vapor permeability is 0.23, frost resistance is 35).

Also, this type of material includes D500 samples with dimensions, 625x250x100, 75x250x625, 50x250x625, 100x250x625 mm (blocks 625x250x100 mm are most often used for the construction of partitions). The density of such material reaches 500 kg / m3. All technical characteristics are the same as for the D500 with tongue and groove.

Ytong also produces reinforced aerated concrete lintels that provide excellent thermal insulation even in the absence of an additional layer of insulation. For load-bearing internal and external walls, as a rule, take the model PN250 with a height of 249 mm or PN 125, the height of which is 24 mm. For internal curtain walls, use PP250 with a height of 49 mm. Also, this manufacturer manufactures prefabricated monolithic floors. They consist of beams with free reinforcement. Such elements are made of reinforced concrete or steel. The length of the parts is determined depending on the spans to be covered. Another component is T-blocks, which are in the form of bushings sandwiched between two side slots. They rest on beams

Ytong also creates arched aerated concrete blocks . With their help, you can bring to life the most daring design ideas. They make it easy to make semicircular interior partitions. Such elements are installed on a thin-seam mortar of the same manufacturer.

The assortment of the company also includes aerated concrete staircase structures. In this case, only heavy-duty concrete of the D600 brand is taken. The manufacturer manufactures stairs of various shapes. They can be installed either with a special adhesive or with tools.

Application

Currently, aerated concrete blocks of this manufacturer are widely used in construction for various purposes. They are often used for the construction of foundations and basements. After all, groundwater often gets on them, and this material does not allow moisture to penetrate inside. Also, aerated concrete blocks are used in the construction of external walls, since coatings made of this material have an increased level of steam permeability and strength. At the same time, they can be erected using only one layer of aerated concrete.

For internal partitions, gas blocks are also taken . They are lightweight, which greatly simplifies installation and reduces the load on the supporting structures. At the same time, the assembly of even the most intricate shape will be simple, because all the connecting elements have perfect geometric outlines and are easily fixed.

This material is also used for floors. The size of the aerated concrete panels allows them to move slightly beyond the walls. They can be used for almost any roof slope. In this case, installation is carried out using a lifting crane; additional equipment is not required for installation.

Reviews

Most consumers note that Ytong aerated concrete blocks are of a high level of quality. Some users speak out about the simple technology of mounting the material, which does not require much effort and time. Consumers also noticed the ideal geometry of each block, which also greatly simplifies installation. Many people talk about a decent appearance of the building material.

However, at the same time, you can also find negative reviews about Ytong aerated concrete. For example, building owners note that it can absorb moisture, so cracks may appear on it over time. Therefore, the material requires additional external protection.
