2)       Large Variety of Sizes

3)       High Fire Resistant

4)       Excellent Thermal Insulation

5)       Great Sound Insulation

6)       Moisture Protection

7)       Termite Resistant

8)       High Workability and Easy Processing

AAC is processed into various types & sizes of block and insulation products and widely used in different industrial and civil construction.

AAC is processed into various types & sizes of block and insulation products and widely used in different industrial and civil construction.

There are two types of concrete:

1)          Compacted Concrete: 1,600~2,400 Kg/m3

2)          Lightweight Concrete:

Lightweight Aggregate Concrete (Ceramsite Concrete, Perlite Concrete):

Porous concrete (foam concrete, aerated concrete ): 400-700kg/m3

Density Comparison Table for most used construction materials: (Kg/m3)

ost commonly used AAC is steam cured silicate concrete. There are two curing methods:

1)          Atmospheric Pressure: Saturate Steam Curing, 100°C

2)          Autoclave Curing: 174.5~200.5°C, 0.8~1.5 MPa

Different AAC Main Components with different Fire Resistance:

AAC can be produced with sand, mineral slag, flay ash, tailings, coal gangue, quicklime (CaO) and cement, as well as various industrial wastes according to actual availability of raw material and production technology.

 AAC can be easily processed and reconditioned. Sawing, plating, drilling, nailing, etc, are applied on AAC to make it more widely applied in construction.
