AAC block/brick making machine
AAC products advantages
1. Services include: design plant, install machines and train
2. Annual capacity: 20,000m3 ~300,000m3.
Aerated concrete brick (or says Foam Block, abbreviate as AAC) is
the light and porous building material. It has light weight,
keeping temperature, can not burn and other advantages. it can be
made into many kinds of bricks, 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
2. Aerated concrete common conception
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).
