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


d
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).

Main Machine List
Cutting machine is the main equipment in the production of aerated concrete. Different
annual output of AAC need different cutting machine. It's absolutely necessary for
promoting the output and quality. Cutting machine series, which our factory produces, can
accomplish six-side cutting in one step. Because of its advanced technology, there is no
need for secondary crane, which reduces the abrasion of body blank arising from multiple
cranes. Therefore, the products are very marketable across the country, and are well
accepted by the customers. Through constant technical reformation, our factory has
developed aerated concrete cutting machine of various types.
