The bricks produced by vacuum brick machines are mainly made of clay, and the production process is simple, but the damage to arable land is relatively serious. In 2015, the country successively introduced policies prohibiting the production and use of clay bricks, and vigorously promoted the reuse of solid waste. And brick products using fly ash as the main production raw material and gypsum and quicklime as the main bonding materials are gradually replacing traditional clay bricks.

Efficient utilization of fly ash, slag, stone powder, desulfurization ash, slag, coal gangue, phosphogypsum, tailings sand, etc. to produce new wall materials, such as autoclaved fly ash bricks, autoclaved lime sand bricks, aerated concrete products, etc.
