AAC is a light weight and porous building material. Cement, lime, slag, flyash, sand and foaming material as raw material, AAC is made by procedure of grinding, batching, pouring, cutting, curing and so on. It is called AAC for those small and even pores inside after foaming. The advantages which make it one of the most popular wall materials are as follows:

1, Light weight
AAC porosity ratio reaches 70%-80% of whole block. Its density is 400-700kgs/m3, 1/3 of solid clay bricks, 1/5 of common concrete blocks. Density of some common building materials is as follows:

Type
AAC Blocks
Solid Clay Blocks
Hollow Blocks
Ceramsite
Concrete Blocks
Normal Concrete Blocks
Density
400-700
1600-1800
900-1700
1400-1800
2000-2400

2, Good heat preservation
With a large number of pores inside, AAC has good heat preservation. Normally, AAC blocks with thickness of 200mm can preserve heat as well as those common solid clay blocks with thickness of 490mm.
Thermal conductivity of some building materials:
Type
AAC Blocks
Solid Clay Block
Hollow Block
Gypsum Board
Common Concrete
Glass
thermal conductivity
0.09~0.22
0.43~0.81
1.0~1.046
0.30
1.50
0.75
3, Good fire resistance without releasing harmful gas
Main materials for AAC are inorganic. It has features of keeping temperature, resisting fire and releasing no harmful gas. With good heat preservation to the steels, buildings made of AAC blocks can only be destroyed by surface when they are on fire.
4, Good workability
Without rough aggregate, AAC has good workability. It can be sawed,cut, drilled freely and bound with other building materials which is favorable for building.
5, Good sound insulation
AAC has good sound insulation for its distinctive large quantities of pores inside.
6, Environmental protection and wide source of raw materials
AAC can be made by slag, flyash, mine waste and other industrial wastes together with lime, cement and gravel which are good for environmental protection.
