Production technology and properties of foamed concrete
Foamed concrete block making machine, is a set of used in the production of: fly ash, sand, stone powder, tailings, slag, construction waste, cement and other as the main raw materials of foamed concrete block equipment.The production line adopts chemical foaming and vertical stirring.The block strength is high, the porosity is even, the molding is stable, the output is high, the cost is low.The production line adopts open mold, dry cutting, yield up to 100%;Production is easy to grasp, cutting specifications can be adjusted, foam concrete blocks can meet the national standards.
The production process of foamed concrete includes: preparation of foam, preparation of foam concretemixture, casting, curing and inspection.
Grassroots clean→Determine thickness and height according to drawing design and technical disclosure requirements- > Water wet- >Foam concrete production→According to the construction sequence pouring molding-→Curing + Inspection and maintenance of finished products.
Product features：
Light:The density of foamed concrete is small, the density grade is generally 300 -1800kg/m3 and the density grade of commonly used foamed concrete is 300-1200 kg/m3.
Good thermal insulation performance: Because foam concrete contains a large number of closed small pores, so it has good thermal insulation performance. Foamed concrete with a normal density grade ranging from 300-1200 kg/m3 has a thermal conductivity between 0.08-0.3w/(moK) and a thermal resistance about 10-20 times that of ordinary concrete.
Good sound insulation and fire resistance: Foam concrete is an inorganic material, will not burn, thus has good fire resistance,in the building use, can improve the building fire performance.
Good overall performance: Can be pouring site construction, and the main project is closely combined.
Low elastic shock absorption is good: The porosity of foamed concrete makes it have low elastic modulus,so that it has good absorption and dispersion effect on impact load.
