Pond ash AAC line,pond ash concrete block production plant,pond ash plant
AAC is a green and sustainable building material and stands for Autoclaved Aerated Concrete, otherwise known as Aircrete. It is manufactured from natural raw materials. Aircrete was developed in 1914 by Swedish engineers. They discovered that adding fine aluminium powder to cement, lime, water and finely ground sand caused the mixture to expand considerably. Most common product densities vary between 350-700 kg per cubic meter. The finished Aircrete product is four to five times the volume of the raw materials used, making it extremely resource-efficient and environmentally friendly. The energy consumed in the production process is only a fraction compared to the production of other materials.

Technological process
(1) all kinds of raw materials storage bin→ (2) measuring and batching → (3) mixing raw material with water → (4) prepared mould (5) → pouring → (6) vesicant and static curing → (7) demoulding → ( 8) rolling-over: horizontal cutting, vertical cutting → (9) be grouped into the autoclaved kettle → (10) high temperature and high pressure conservation → (11) out of autoclaved kettle for finished product → (12) testing finished product → (13)packaging → (14) stacking storage → (15) out of factory
