The autoclave concrete after steaming the grreen body can get a certain conglutination, and glass severing machine can sparate the cutted concrete block along with kerf and stacked up together, so that will not damage block when packing and transporting, and improve rate of finished product.
Sand AAC line 2015 new fly ash AAC line
1. Fly ash sand AAC line simple introduce
AAC block (light brick ) is the light and porous buidling material. It has
Light keeping temperature cant burn and other advantages. It can be made into many kinds
Of bricks(for example: 600X200X100, 80X80X180, 240X115X53, 600X200X125), they could
Be used industry building and common building. They are more and more popular in the
World. In the future, they will replace the Clay brick completely.
2. Fly ash sand AAC line common conception
Common concrete density is usually 1600-2400kg/m3, but Areated concrete are 500kg/m3, 600kg/m3
, 700kg/m3. It has not the big grain, main 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 water to a special slop, then add the aluminum dust and the additive. Make the
Aluminum dust and the special slop have a Chemical reflect. Then produce Hydrogen to make
The concrete slop to expanding or swell, foam. Next, put them into the curing room to
Concreting cutting steaming curing, last, there will bacome the light brick, the porous rate
3. Fly ash sand AAC line advantage
Areated concrete density is usually 400-700kg/m3, (according the market in produce ), same as
1/3 of clay brick and 1/5 common concrete. So use the Light brick can reduce the weight of
The build more, and also reduce the beam of roof and pillar press best. Then you can see, it
Can save the material and cost, it also fighting shaking.
It has many are porous, the delivery hearting coefficient is 0.9-0.22W/(mk), the same as 1/4
Or 1/5 of clay brick, so it is best materials now in the world.
