Common concrete density is
usually ********0kg/m3,but Areated concrete are
**0kg/m3,**0kg/m3,**0kg/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 ****0%.
