Autoclaved aerated concrete blocks Manufacturer's introduction Autoclave Aerated concrete block It is a kind of porous concrete product made of fly ash, lime, cement, gypsum, slag, etc. as the main raw materials, with appropriate amount of air entraining agent, conditioner, bubble stabilizer, through the process of batching, mixing, pouring, static stop, cutting and high-pressure steam curing.

1. Light weight: the dry bulk density of this product at different grades is 400-600kg/m3, which is 1/3 of red bricks and 1/4 of cement bricks. Therefore, it can effectively reduce the dead weight of buildings, reduce the input of foundation and structure, and reduce the labor intensity during construction.

2. High strength: because the product size is accurate and six sides are cut and thin layer mortar is used for masonry, the strength application coefficient is greatly improved. The masonry strength of the block is about 80% of the strength of the block itself (only 30% for red bricks).

3. Environmental protection: this product is made of fly ash, cement, lime and gypsum as the main raw materials. The inorganic environmental protection wall materials do not produce any pollution in the process of consumption, transportation and application. It is a good green building material product without radioactivity.

4. Size accuracy: advanced consumer technology and equipment ensure the accuracy of product dimensions, and the length, width and height of products are higher than the requirements for inferior products in national specifications.

5. Economical type: because of the reduction of building weight, the cost of foundation and structure disposal can be greatly reduced, and the comprehensive cost can be reduced. Because the high-precision surface can be directly plastered, the data used for surface painting and the thickness of artificial products can be reduced. The building application coefficient can be increased, and the thermal insulation performance of the applied surface is good, which can greatly reduce the operating cost of the building.

6. Impermeability: the internal small holes of the product are all independent sealing holes with a diameter of about 1-2mm, which can effectively prevent moisture diffusion. The height of the water column soaked in the standard impermeability test method is only 1/4 of that of the red brick.

7. Fireproof performance: both the raw materials and the product itself are inorganic and never extinguish. Experiments show that this product is an ideal fire protection material. The fire protection ability of 10 cm thick walls can reach more than 3 hours, so this product is widely used as a firewall.

8. Good sound insulation: according to the wall thickness and surface treatment method, the wall can be soundproofed to 30-52 dB, and it is also a good sound absorption material.

9. Thermal insulation: when 1/7 of the thermal conductivity of the brick masonry of this product is used as the peripheral structure, it can meet the thermal insulation and energy saving requirements of energy-saving residential buildings in China without auxiliary thermal insulation data. With 4-5cm products, it can achieve the thermal insulation effect of a brick wall.
