It generally includes discarded concrete, bricks, wood, plastic, fine steel bars, metal, cloth, etc. Now construction waste is also used as raw material for brick making. Construction waste is sorted, crushed and screened as recycled aggregate, and is measured and mixed with ecological cement (mainly prepared from solid waste such as high-calcium fly ash, slag and desulfurized gypsum), antifreeze aid and water in proportion. After processing by construction waste treatment equipment, the construction waste can be produced by cement brick making machine to produce high-performance standard bricks.
