Aerated concrete manufactured by stone material waste and manufacturing method thereof
The invention discloses aerated concrete manufactured by stone material waste. The aerated concrete is manufactured by a pretreated stone powder material, slag ash, cement, unslaked lime, desulfurized gypsum, powdered aluminum paste and a hyper-dispersant, wherein the pretreated stone powder material is produced by crushing, mixing and grinding stone material machining waste and waste aerated concrete building blocks. The stone material machining waste and industrial wet furnace slag ash are machined and re-treated, the utilization problem of a stone material and other waste is effectively solved, energy is saved, and environment is protected. A related manufacturing process is simple and low in cost. The hyper-dispersant can effectively improve the dispersing performance of concrete slurry, the viscous resistance of stone powder granules is reduced, and early-stage coordination between aeration and densification of the slurry is ensured, so that the aerated concrete has the advantages of being low in drying shrinkage value, good in thermal insulation property, high in compressive strength and the like. In addition, natural stone material waste, waste aerated concrete and furnace slag ash are recycled to slow down soil degradation, underground water pollution, dust pollution and other environmental problems, and the aerated concrete is suitable for popularization and application.
