Aerated Autoclaved Concrete Brick Machine Plant


1, Introduction of Aerated Autoclaved Concrete Brick Machine Plant
Areated concrete block (light block) is the light and porous building 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)
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 become the light brick, the porous rate is 70-80%.
2, main features of Aerated Autoclaved Concrete Brick Machine Plant


1. Light weight, Areated concrete density is usually 400-700kg/m3, (according the market in produce ), same as 1/3 of clay block and 1/5 common concrete. So use the Light block 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.
Have many kinds material, have lowest waste

Capacity and Land Area Introduce
1. For AAC Machine line, according capacity: there have 50000m3/year, 100000m3/year, 150000m3/year, 
200000m3/year, 300000m3/year. According 330 days to count capacity per year, they are means per day
 produce 160m3, 310m3, 460m3, 610m3, 910m3.
2. For Land requirement, usually for 50000m3/year and 100000m3/year, we need workshop area 2000m2, 
and total land at least 18000m2 more bigger, more better. 
Usually for 150000m3 AAC line, we need workshop about 2500m2, total land at least 20000m2 more bigger 
more better.
Usually for 200000m3-300000m3 AAC line, we need workshop about 3000m2, total land at least 25000m2 more bigger more better
