Autoclave Aerated Concrete Brick

1. Introduction

Aerated concrete brick (or says Foam Block, abbreviate as “AAC”) is the light and
porous building material. It has light weight, keeping temperature, can’t burn and other
advantages. it can be made into many kinds of bricks (for example : 600×200×100,
80×80×180 , 240×115×53, 600×200×125 ) ,it could be used industry building and
common building . It is more and more popular in the world construction field. In the
future it may be replace the Clay brick completely.

Common concrete density is usually 1600-2400kg/m3, but Aerated concrete are
500Kg/M3, 600kg/m3, 700kg/m3. It mainly use silicon material (for example: coal ash ,
sand , stone dust and others ) ,through making the material small for example sand, they
can be used directly if has enough degree of small (for example coal ash. Mixing calcium
material, lime, cement, and water together, then adds the aluminum dust and the other
additive. The aluminum dust and the above materials will have a Chemical reaction. Then
it will produce Hydrogen to make the concrete slop expanding (or swell) and form some
foam inside. Next, put them into the pressured steam room. Last, there will become the
light brick (or say foam block). The final products has the porous rate is about 70-80%.


3. Advantages of AAC Products:

A. Light weight
Aerated concrete density is usually 400-700kg/m3, it is about 1/3 of the clay brick
weight and 1/5 common concrete block weight. Using the Light brick can reduce the
weight of the build and also reduce the loading of the beam of roof and pillar. You can see,
it can save the material and cost, it also fighting against shaking.

B. keeping temperature

It has many porous, the heat transition coefficient is 0.9-0.22W/ (mk), it is just
about 1/4 or 1/5 of clay brick, so it is the best materials for keep the room temperature now
in the world.

C. There are many kind materials even waste material can produce the AAC products, for
example: coal ash, sand, waste mine material, coal stone, stone dust, and other silicon
materials.

D. Save the land and energy
When you produce AAC products it use the energy (or fuel) just 11% of the clay
brick Products.

E. The AAC Products has one useful advantage is the “Plasticity”. As it is has more
foam
Inside and weight is lighter and not so hard so it is easy to be produced in every kind
shape and when it is re-assemble or re-production it will be more suitable for sawing,
paring, drilling, and clinch (clench).

F. Sales Profit: AAC Products market profit it good then common brick and cement
blocks, especially the AAC Board products (Plate shape AAC Products).
The end products are:
