Autoclaved Aerated Concrete Block Production Line
What is the Autoclaved Aerated Concrete?
·Aerated concrete is a porous silicate product made of siliceous and calcareous materials as the main raw materials, mixed with aerating agent, stirred with water, formed pores by chemical reaction, and made through the process of casting and molding, pre-cultivation and cutting, autoclave maintenance, and so on.
What are the advantages of AAC bricks?
·Light weight: 400~700kg/m³
·Good thermal insulation performance: thermal conductivity 0.09~0.22W/(m.k)
·Good fire resistance without emission of harmful gases
·Machinability
·Wide source of raw materials, high production efficiency, low energy consumption
Our Advantages
·It can realize mixing and grinding to prepare cementitious materials, and effectively improve the stability of casting; infusion cylinder casting mixing, so that the mixing time is shortened, and greatly improve the uniformity of mixing.
·Staggered dosage process, the dosage building is divided into two, staggered arrangement of high and low, to simplify the arrangement of equipment and architectural structure, to meet the staff space and equipment layout requirements.
·Integrated layout process, the batching, casting, pre-culture, cutting, de-bottoming, grouping and other processes are arranged in the same workshop, the use of hydraulic lifting and conveying equipment, so that the walking rail and the main body of the workshop are separated, reducing the height of the workshop, the use of the U-row layout, to avoid the dead ends of the building,shorten the return journey of wastewater and waste slurry, reduce the operating space for the operation of the workers to improve the efficiency of the work and other advantages.
Process Flow and Material
Sand (65-70%): The core raw material of AAC product; the main resource of silica-aluminum components; correspond with JC409-91,the clay should less than 4%.Lime(12-20%): One of the main raw materials of fly ash AAC; the main effect is to provide efficient calcium oxide with cooperation of cement making calcium oxide react with SiO2, Al2O3 in hot water then to produce calcium silicate hydrate. Therefore, lime is also the main resource of strength. Effective calcium oxide of lime should not less than 65%, over 80% is perfect and should accord with JC/T621-1996.
Cement(8-10%): This Project aims to utilize OPC cement as main binder material. It will give faster strength to the bricks, besides giving improved consistent quality. It also ensures a better cost effectiveness for the same. Using OPC will be a standardized practice. The other prime advantages of using OPC (compared to other binders) is it's easy availability locally through nationwide Retail Network of Cement Companies.
Gypsum(1-2%): Gypsum is the foaming regulator in AAC which dispels quicklime and postpones slurry's densification.CaSO4 should be more than 70%.
Aluminum Podwer(0.074%): It is the forming agent type and recommendation for supply depend on raw materials and mix formula:A lot has been said about this raw material in this Project Profile itself. But this Raw material is freely available in Thermal Power plants. There are no taxes on this item whatsoever. Transportation charges are only to be attended by the entrepreneur.
