Aerated concrete blocks Ytong: types and characteristics

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 the products of the company Ytong.

Aerocrete German company Ytong consist of a special mixture, which consists of several elements.

When mixed, they form a special porous structure of parts. It:

• quartz sand;
• Portland cement;
• aluminum powder and suspension;
• crushed lime (it can be both slaked and unslaked);
• water (only approved by the State Standard).

The basis of the gas block is quartz sand. Also important are powders and suspensions of aluminum.They form aluminum oxide and hydrogen, which gives the material porosity. 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 furnaces, in which they are strongly compressed at a set level of moisture and temperature. After that, it turns out heavy-duty construction products that can withstand almost any chemical reaction.

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

Ytong gas-block have excellent sound insulation properties. Due to the cellular surface, blocks can significantly reduce excess noise. Due to this, walls of such material allow to reduce the penetration of sounds inside the building.

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

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 unit provides air circulation and evaporation of excess moisture, which stops the formation of mold and fungus on the surface.Excellent vapor permeability allows you to create a favorable microclimate inside the building. However, it should be remembered that, due to too much porosity, aerated concrete in rooms with too high levels of humidity can be laid only 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. With strong mechanical effects, it can break down. The blocks also have a lower level of compressive strength due to the too low thermal conductivity. Therefore, if the permissible value is exceeded, the structure may be damaged.

Today, Ytong produces two types of gas blocks:

• smooth;
• tongue-and-groove.

Such blocks are used for exterior and interior decoration (for partitions, walls, lintels, ceilings, restoration works). With the aid of the tongue-and-groove structure, all the parts can be easily interconnected without using adhesive compositions.

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

The tongue-and-groove blocks include the D400 model (its dimensions can be 375x250x625, 300x250x625 mm). As a rule, it is used for finishing external walls without insulation. The density of this variety is 400 kg / m3. Vapor permeability is equal 0,23, and frost resistance - 35.

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

The smooth version of aerated concrete Ytong are models D400whose size can be 150x250x625, 200x250x625, 240x250x625, 250x250x625, 300x250x625, 375x250x625, 400x250x625, 500x250x625 mm. The density of such building gas blocks reaches 400 kg / m3. Their technical specifications are the same as those of the groove-grooved D400 (vapor permeability is 0.23, frost resistance is 35).

Also, D500 samples with dimensions of 625x250x100, 75x250x625, 50x250x625, 100x250x625 mm (blocks 625x250x100 mm are most often used for the construction of partitions) also belong to this type of material. The density of this material reaches 500 kg / m3. All the technical characteristics of it are the same as those of the D500 models with a groove-comb.

The company also produces Ytong reinforced aerated concrete lintels, which provide excellent thermal insulation, even in the absence of an additional layer of insulation. For bearing internal and external walls, as a rule, they take the model PN250 with a height of 249 mm or PN 125, whose height is 24 mm. Apply PP250 49 mm high to the internal curtain walls. 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 parts is determined depending on the overlapped spans. The other components are T-blocks, which have the form of inserts sandwiched between two side slots. They lean on beams

Ytong company creates and arc-shaped aerated concrete blocks. With their help, you will be able to realize the most daring design ideas. They make it easy to make a semicircular interior partitions.Such elements are installed on the thin-seam solution of the same manufacturer.

Currently, aerated concrete blocks of this manufacturer are widely used in construction for various purposes. Often they are used for the construction of foundations and basements. After all, they often get groundwater, and this material does not allow moisture to penetrate. Also, aerated concrete blocks are used in the construction of external walls, since coatings of this material have an increased level of vapor conductivity and strength. In this case, they can be built using only one layer of aerated concrete.

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

Most consumers note that aerated concrete blocks brand Ytong have a high level of quality. Some users are talking about a simple material editing technology that does not require a lot of time and effort. Consumers have noticed the perfect geometry of each unit, which also greatly simplifies installation. Many talk about the decent appearance of building material.
