1. Light capacity: the dry capacity of lightweight refractory brick is only 500-700Kg/m*3, which is 1/4 of ordinary concrete, 1/3 of clay, and 1/2 of hollow block, because its bulk density is smaller than that of water , commonly known as aerated concrete floating on the water surface, the use of this product in construction can reduce the self-weight of the building and greatly reduce the comprehensive cost of the building.
2. Heat preservation and heat insulation: During the manufacturing process of aerated concrete, tiny pores are formed inside, and these pores form an air layer in the material, which greatly improves the effect of heat preservation and heat insulation, so that the thermal conductivity of aerated concrete is 0.11- 0.16W/MK. The thermal insulation effect is 5 times that of clay bricks and 10 times that of ordinary concrete.

3. Small shrinkage value: due to the use of high-quality river sand and pulverized coal as siliceous materials, the shrinkage value is only 0.1--0.5mm/m, and the excellent material with small shrinkage value ensures that your wall will not crack.
4. Impermeability: The pore structure of this product makes it poor in capillary action, slow in absorbing water and conducting moisture, and the time required to absorb water to saturation with the same volume is 5 times that of clay bricks. Environmental protection: The manufacturing, transportation, and use processes are pollution-free, protect arable land, save energy and reduce consumption, and are green and environmentally friendly building materials.
5. Earthquake resistance: Lightweight refractory bricks are used in the same building structure to improve the earthquake resistance level than clay bricks.

6. Durability: The long-term strength of air-entrained concrete is stable. After one year of exposure to the atmosphere of the specimen, the strength has increased by 25%, and it remains stable after ten years.
7. Processability: This product is light in weight and has various specifications and sizes, which is convenient for nailing, drilling, chopping, sawing, and planing for laying pipelines, and using expansion pipes on the wall can directly fix hanging cabinets, air conditioners, smoke machines, etc. , Bring convenience to your water and electricity installation and home decoration.

8. Fire resistance: The fire resistance is 700 degrees, which is a first-class refractory material. The fire resistance of 100mm thick blocks reaches 225 minutes, and the fire resistance of 200mm thick blocks reaches 480 minutes.
