Aerated Concrete Production Line  

aerated concrete production line mainly uses fly ash (slag) as the raw material, lime and cement as the cementing material, and aluminum powder as the aerating agent. The aerated concrete is produced by crushing, measuring, mixing, pouring, resting, cutting, steam curing and other processes. Aerated concrete is a new type of wall building material, which has the advantages of light weight, heat preservation, heat insulation, energy saving, waste, environmental protection construction, convenient and fast. Because it contains a large number of uniform and small pores after gas, it is named aerated concrete.

  AAC aerated concrete raw materials  

autoclaved aerated concrete plate (block) is made of siliceous materials (sand, fly ash, silicon-containing tailings, etc.) and calcareous materials (lime, cement), etc. as the main raw materials, and then according to the structural requirements, different amounts of steel bars, air-generating agent (aluminum powder), etc. are added, and the autoclaved aerated concrete plate (block) with porous crystals is produced by reaction after high temperature, high pressure and steam curing.

aerated concrete block raw materials:
1. Sand (65-70%): the core raw material of AAC products; the main resource of silicon-aluminum components; according to the JC409-91, the clay should be less than 4%.
2. Lime (12-20%): one of the main raw materials of fly ash AAC; Its main function is to provide efficient calcium oxide with cement, so that calcium oxide reacts with SiO2 and Al2O3 in hot water to form calcium silicate hydrate. Therefore, lime is also a major source of strength. The effective calcium oxide content of lime should not be less than 65%, and more than 80% is the ideal value, which should comply with JC/T621-1996.
3. Cement (8-10%): OPC cement is proposed to be used as the main bonding material in this project. It will provide faster strength to the bricks while improving consistent quality. It also ensures better cost-effectiveness. The use of OPC will be a standardized practice. Another major advantage of using OPC (compared to other adhesives) is that it is easily available locally through the nationwide retail network of cement companies.
4. Gypsum (1-2%): Gypsum is a foaming regulator in AAC, which can disperse quicklime and delay the densification of slurry. CaSO4 should be greater than 70%.
Aluminum powder (0.074%): This is the type of forming agent and supply proposal determined according to the raw material and mixed formula.
Autoclaved aerated concrete is based on the calcium-silicon hydration reaction. In addition to traditional sand, there are many types of solid waste that can be used to produce AAC, such as slag, tailings, ceramic tailings, etc. The most common solid waste is fly ash. The utilization of a large amount of fly ash and solid waste is very important for environmental protection.

  aerated concrete products show  

aerated concrete production line, fly ash or silica sand, river sand and slag are ground into slurry with water, powdered lime, appropriate amount of cement and aluminum paste are added and mixed into the mold frame. After static foaming and curing, blocks or plates of various specifications are cut into blocks or plates, which are fed into autoclave by steam curing truck and cured by high temperature and high pressure steam to form porous and lightweight concrete products.

  aerated concrete product application  

aerated concrete blocks are often used in the interior and exterior walls of residential buildings, especially non-load-bearing walls. Because of its good thermal insulation properties, it is also often used as a thermal insulation material for roofs and floors. Such as office buildings, shopping malls, hotels, hospitals, schools and other public buildings walls, floors, roofs and other parts, the use of its sound insulation performance to reduce noise interference, improve the use of comfort.
