aac concrete block

Introduction of AAC Block:

Autoclaved Aerated Concrete (AAC) Block, also called Light Block, used siliceous (fly ash, sand, slag) and calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, curing, cutting, autoclaving, separating and packing to make into the final products. It is new type & environmental construction material and widely used for industry and civil building construction. AAC Block is the most mature technology of production and application in the worldwide nowadays.

Advantages & Features of AAC Block:

1. Light Weight: 300~800kg/m³

2. High Intensity: 3.5~10.0Mpa

3. Good Thermal Insulation Property: 0.1~0.20W/(m·k)

4. Keeping Temperature, Heat Resistant, Fireproof

5. Good Sound Insulation

6. Earthquake Proof

7. Good Machinability

8. Conveniently Mechanized Construction
