Ceramsite concrete wall panels: characteristics

Today claydite concrete is used in construction quite widely. It is compared with concrete, but the first material is characterized by more outstanding technical characteristics, among which are a low level of thermal conductivity, resistance to chemicals and increased moisture resistance. But claydite concrete has a porous structure, therefore it is not necessary to use it for erection of dimensional objects and construction of foundations. Claydite-concrete wall panels can be found on sale today. Their characteristics and features will be discussed below.

Description

Panels made of expanded clay concrete have the appearance of block elements that have standard dimensions. They depend on the type of cutting and vary from 300 to 7200 mm, as to length, and from 300 to 8100 mm, which is true for height. Products are widely used in the construction of structures, where they perform the role of internal partitions and external walls.

The claydite-concrete panels act as a material for filling the frame in reinforced concrete objects. Keramzitobeton is a lightweight concrete, as a filler of which the expanded clay stands. The connecting element is cement. Some technologies include the addition of lime and gypsum in the production process. The panels also have sand in the composition. Depending on the method of manufacture, as a result, you can get materials with different density. You can classify panels on:

• lungs;
• Large-porous;
• Heavy.

The first option is used in the manufacture of structural, structural, heat-insulating and heat-insulating products.

Classification of expanded clay panels

Keramzitobetonnye wall panels can be classified on different grounds. By appointment, they can be for:

• Attic;
• Socle;
• Above-ground floor.

According to the static scheme of work, products can be divided into self-supporting, load-bearing and hinged. Among the advantages of the latter are reliability and low cost. Among other things, the hinged panels have high sound and heat insulation features, have good strength and moisture resistance, and also provide an accelerated pace of work.

Ceramsite concrete wall panels are manufactured according to state standards 11024-84, according to which they can be external, layered, partitions. External are used for unheated buildings, are made of different brands of concrete. Laminated are obtained from heavy concrete, to which is added a heat-insulating layer. The partition walls can be made of different types of concrete.

According to the device, the products described should be divided into prefabricated and solid. The first are made up of the original elements by the type of blocks that are joined together by a solution or glue. As a joining technology, the welding technique can be used. Most often they are used where the requirements for crack resistance are high.

Variety of panels depending on the number of layers

Ceramsite concrete wall panels can also be classified according to the number of layers. So, they are:

• Single-layer;
• Two-layered;
• Three-layer.

A screen is called an air gap. If we are talking about single-layer panels, they have low qualities of thermal conductivity. The panels can also be subdivided into sections of walls, they can be uniform, angular, strip and vertical.

Specifications

As mentioned above, claydite-concrete panels are classified according to a number of characteristics, so the manufacturers accepted a lot of notation. If you see the marking of HCHS, then before you - an external single-layer wall panel of single-row cutting, which can become a carrier. The fact that in front of you an external single-layer wall panel of horizontal cutting, indicates the marking of 1NGO. Two-layer wall exterior panels of horizontal cutting - these are products with the designation 2NGP.

If the production is carried out according to the state standards 23009, then this indicates that the numbers and letters indicate the type of panel, and the dashboard refers to the class of expanded clay concrete according to the compressive strength. The symbols in the third group indicate additional characteristics, for example, the presence of cutouts and holes. If you saw the marking of 2NSN 40.27.30-15K, then before you a double-layered outer panel, which has a single-section cut. Its length is 3995 mm, while the height and thickness are 2650 and 300 mm, respectively. As for the class of compressive strength, these products correspond to B15.

In addition to the characteristics

The thickness of claydite-concrete wall panels was mentioned above, but this characteristic is not the only one to be aware of before acquiring the material described. As for the thermal conductivity, for these products it is similar to brickwork, the thickness of which varies from 100 to 120 cm.

The number of layers influences the density. Single-layer panels have a density in the range of 900-1100 kg / cm ³ . The mark of the concrete component affects the weight, the same can be said about the dimensions. Products can reduce the weight of the reinforced concrete structure. You may also be interested in strength, for these panels it is quite high and can be in the range of 35-100 kg / cm ² . Claydite-concrete wall panels, the sizes of which are mentioned in the article, are quite hardy, they are able to undergo about 500 cycles of freezing and thawing.

In addition, the coefficient of thermal conductivity

Thermal conductivity of wall claydite-concrete panels can vary depending on the purpose of the products. If we are talking about thermal insulation panels, then they are used for insulation in the process of construction. The density of such a material can vary between 400-600 kg / m ³ , as to the compressive strength, it is 7-25 kg / cm ² . But the thermal conductivity is equal to 0.10-0.17 W / (m * K).

On sale it is possible to meet the construction and thermal insulation products, which are used for the construction of objects where it is required to reduce the mass of structures. Excellent such units have proved themselves also because they have impressive dimensions, their density after the set strength can be equal to 700-800 kg / cm ³ . This provides the material with high strength, which is especially true if compared with insulation products. However, the thermal conductivity in this case is higher and can be equal to 0.22-0.45 W / (m * K). Such claydite-concrete wall panels, the GOST for manufacturing of which was mentioned above, have less impressive frost resistance, it can correspond to the limit of 20-90 Mp3.

Characteristics of constructional expanded clay concrete

Such blocks are the most durable, they are used for the erection of houses and industrial premises. The density is quite high and depends on the type of material. This figure can reach a value of 1800 kg / m ³ . In the hardened state, the material has a compressive strength of 100 kg / cm ² . Frost resistance may be equivalent to 100-400 Mp3. But the thermal conductivity is even higher and reaches a mark of 0.55 W / (m * K).

Conclusion

Wall panels are internal claydite-concrete - this is just one of the varieties of the material described. Panels can be designed for insulation, erection of structures and structures, and also used in solving problems aimed at reducing the mass of buildings and structures.
