Sand aerated block Functional features

1. Light weight and high strength

The absolute dry unit weight is 500-700kg/m3, which is 1/4 of the standard brick and 1/3 of the clay brick. It can effectively reduce the dead weight of buildings, reduce the investment in foundation and structure, and is very suitable for frame structures in various industrial and civil buildings, as well as buildings in weak geology.

2. Thermal insulation

The thermal insulation performance is 7 times that of clay bricks, 10 times that of ordinary concrete, and 3-4 times that of solid clay bricks. It is warm in winter and cool in summer, greatly improving living conditions, saving energy, and increasing the use area of buildings.

3. Impermeable and waterproof

The internal holes of the product are all independent closed holes, which can effectively prevent moisture diffusion. If special adhesive is used for masonry, the product mortar joint is 3/4mm, which further improves the overall impermeability of the wall.

4. Fire retardant

The raw materials and products of this product are inorganic and incombustible. It will not lose strength at 700 ℃ and will not produce toxic gas in case of fire. The wall with a thickness of 10 cm can prevent fire for more than 4 hours, which is an ideal first class fireproof building material.

5. Sound insulation and absorption

It has a good sound insulation effect. According to its thickness, it can sound 40-50 decibels. It is also a good sound absorption material.

6. Dimensions The length, width and height error of the product is within the range of 2-3mm, which makes it possible to promote the application of thin layer mortar.

7. Green and environmental protection

It is a green environmental protection product and can meet strict European environmental protection requirements.

8. Convenient construction

It can be built continuously, greatly improving labor efficiency. Good field processing performance, sawing, planing and size trimming. When installing water and electricity facilities, drilling, grooving and opening are convenient and fast. Air conditioners, water heaters and other heavy objects shall be installed reliably.

9. Economical and practical

The cost of foundation and structure treatment can be greatly reduced due to the reduction of building weight. Because of its precision, the surface can be directly embedded in batches, reducing the materials and labor required for surface painting; Because the thickness of the product is relatively small, it can improve the building utilization coefficient and increase the use area.
