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 .
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%
