INTRODUCETION of CLC BLOCK MACHINE :

1. Introduction

Areated concrete block (light block ) is the porous and light buidling material. It has light can maintain temperature, can' t burn and other advantages. It can be made into lots of blocks for example: 600× 200× 100,80× 80× 180,240× 115× 53,600× 200× 125), they could be used in industry building and common building. They are becoming more and more popular in the world. In the future, they will take place the Clay block completely.

2. Areated concrete common conception

usually, the density of the common concrete is 1600-2400kg/m3, but Areated concrete is 500kg/m3,600kg/m3,700kg/m3. It doesn' t have the big grain, mainly use the silicon material (for example: sand, coal ash, stone dust and others ), finally making the material get smaller, for example sand, they can be used directly if it 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 expand or swell, foam. Next, put them into the curing room to concrete cutting steaming curing, last, there will become the light brick, the porous rate is 70-80%.

 

3. Advantages of this CLC block machine:

1 light weight , Areated concrete' s density is often 400-700kg/m3, same as 1/3 of clay block and 1/5 common concrete. So use the Light block can reduce the weight of the build, besides, it also can reduce the beam of roof and pillar press best. Then you can know, it can save the cost and material, it also can fight shaking.

2 keeping temperature: It has many porous parts, the delivery hearting coefficient is 0.9-0.22W/(mk), the same as 1/4 or 1/5 of clay block, so it is the best materials now in the world.

Have many kinds of material and the lowest waste.

 

Main Material: coal ash sand waste mine material coal stonestone dust and other silicon materials.
