Product Description

 Light Weight Concrete AAC Block Making Machine 

 

Product Description

 

PRODUCT DESCRIPTION:

1. AAC(Aerated Autoclaved Concrete Block Machine line)introduce

(1).  introduction
  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 : 600×200×100,600×150×100 , 600×300×200, 600×200×150 ) ,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).Areated 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). Advantages
     light weight
     Areated concrete density is usually 400-700kg/m³,(according the market ti 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 :A:sand/ Flyash 65-70%  B:cement  12-15%   C:Lime powder 12-15%   D: Gypsum 3-5%   E: Aluminum  0.5kg/m3 aac block
