Sand AAC Plant Introduction
Autoclaved Aerated Concrete (AAC) Block, also called Light Block, used siliceous (fly ash, sand, slag) and calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, curing, cutting, autoclaving, separating and packing to make into the final products. It is new type & environmental construction material and widely used for industry and civil building construction. AAC Block is the most mature technology of production and application in the worldwide nowadays.

Sand AAC Plant Advantages & Features
1. Light Weight: 300~800kg/m3
2. High Intensity: 3.5~10.0Mpa
3. Good Thermal Insulation Property: 0.1~0.20W/(m · k)
4. Keeping Temperature, Heat Resistant, Fireproof
5. Good Sound Insulation
6. Earthquake Proof
7. Good Machinability
8. Conveniently Mechanized Construction

Sand AAC Plant Working Principle-CUTTING MACHINE:
Yufeng patent turning hoist bring the mould with green block body turning 90 degree in the air, then put it on cutting car, block body with side plate settled on the cutting car together, then moving controlled by electric motor, finish lengthwise cutting, groove milling, horizontal cutting through lengthwise cutting system. The cutting car continuously walking until arrival the central position of vertical cutting system, crosscut shelf vertically finish cutting from top to bottom. Cutting car then walk to the position of grouping hoist, organized into groups and hoist hang the group block body with side plate to the autoclaving car into autoclave, cutting car returning to the primitive position and ready for next cutting circulation.

AUTOCLAVED AERATED 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%.
