Autoclaved Aerated Concrete Line(AAC),for this highly sophisticated manufacturing process, Shandong Dongyue Building Machine Co.,Ltd has all the components and technology available.The manufacture of aerated concrete places great demands on the dosing of raw materials, the supervision of the fermentation process and the control of the following production steps. Many years of experience and the deployment of the latest automatic control algorithms in our control components guarantee the quality of the finished products.
The basis for continuous high quality
Aerated concrete is produced from quartz sand, lime, cement, gypsum (anhydrous),and water.The process starts with quartz sand being milled in a wet ball mill into a fine sand slurry which is then stored in slurry silos with an integrated stirrer.It is important to keep the defined density, which is controlled either manually or automatically. Sand slurry, recycled slurry, lime, cement, gypsum, aluminum and water are added to the mixer according to the desired product recipe.Immediately after the mixing the pre-positioned moulds are filled and subsequently transported to the fermentation area. Here the mixture starts reacting by producing fine pores, allowing the mass to harden into an aerated concrete cake.
Consistent precision
The fermentation process produces hydrogen, resulting in the creation of billions of tiny pores in the concrete cake. At the end of the process the cake is left with an enormous number of air cells. Simultaneously the aerated concrete cake starts to harden.As soon as the material has enough resistance to be cut, the aerated concrete cakes are demoulded and placed onto the cutting line. Here they are frst calibrated, profiled, and cut both horizontally and vertically

B. Aerated Concrete Common Conception
Common concrete density is usually 1600-2400kg/m3, but aerated concrete blocks 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 having enough degree of fineness (for example coal ash).Mixing calcium material, lime, cement, water to a special slop, then add the aluminum dust and 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. porous rate is 70-80%( according to the line photo).

1. light weight:Aerated concrete density is usually 500-700kg/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 .
2. 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.
3. have many kinds material, have lowest waste: Main material:coal ash, sand, waste mine material, coal stone, stone dust and other silicon materials
Save more soil, when produce 10000 m3 light weight brick, will use 4200 Ton coal ash ,and save coal ash using area 400m2, save burning clay brick 3500m2.
4. high anti-seismic ability:AAC concrete blocks weight is light,good overall performance,because of small inertial force,having certain aseismic capacity.
5. good processing performance:Aerated concrete block machine has very good processing performance, can be sawed, dug, nailed,milled,and drilled.bring a lot of convenience and flexibility to construction.
6. certain therm-stability:AAC blocks compression strength grow slightly at the temperature is at below 600 degree.when the temperature is above 600 degree,its compression strength close to normal temperature.Fire proof performance can reach national first-level fireproof standard.
7. Good sound insulation:AAC blocks internal structure is like bread, evenly distributed a large amount of closed porosity,so having sound absorbing performance that common building material don't have.
8. High adaptability:AAC blocks can be made according to local different raw materials, different conditions.raw materials could choose local river sand,fly ash and ore sand..., Could recycle , favorable at environmental protection,changing waste material into wealth.
