AAC  LINE INTRODUCE 

1.AAC BLOCK MACHINE SIMPLE INTRODUCE

    Areated concrete brick (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:600×200×100,80×80×180,240×115×53,600×200×125),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.AERATED CONCRETE 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 is 70-80%.

3.ADVANTAGE

     light weight

     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.

     keeping temperature

     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.

have many kinds material,have lowest waste

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