AAC Block plant( Tianyuan brand)

1. Advantages - Tianyuan AAC Block:

Being light-weight AAC drastically reduces the building load, resulting into reduction in steel( up to 27%) and cement(up to 20%) structural cost saving. Being 8times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus saving mortar up to 66%.

2. Introduction- AAC Block Plant

Autoclaved Aerated Concrete (AAC) Block, also called Light-weight Block. Use silicate (fly ash/sand/slag) and calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, curing, cutting, hardening, separating and packing made into the AAC BLOCK. 

3. AAC plant(tianyuan brand) Planning and design:

 Factory covers an area of 6000~30000m2.(workshop at about 1800~3000m2)
