1.instroduce: Autoclave aerate concrete brick(AAC) is the light and porous building material.It has light keeping temperature cant burn and advantage.it can be made into many kinds of brick.they could be used industry building and common building ,they are more and more popular in the word.in the futhure.They will replace the clay brick completely. 2.Aerate concrete common conception common concrete density is usually 1600-2400kg/m3,but aerate concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the grain,main use silicon material,through making the material small for examplesand,theycan be used directly if has enough degree of small.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 become the light brick.the porous rate is 70-80%. 3.Advantages Light weight Aerate concrete desity is usually 300-800kg/m3,(according the market ti produce),same as 1/3 of clay bbrick and 1/5 common comcrete,So use the light brick can reduce the weight of 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 material now in the world. Have many kinds material,have lowest waste Main material:sand,fly ash Save more land When produce 1000m3 light weight brick,will use 4200Ton coal ash,and save coal ash using area 05 mu,save burning clay brick 5mu. 4. 1.
