Powder solid waste granulation baking-free brick and preparation method thereof
The invention discloses a powder solid waste granulation baking-free brick and a preparation method thereof, and belongs to the technical field of solid waste building material resource utilization. The preparation method comprises the following steps: taking 80-90% by weight of powder solid waste and 10-20% by weight of a hydraulic cementing material, and adding water and a water reducing agent for granulation to prepare solid waste particles with the particle size of 1-30mm; taking 70-80% by weight of powder solid waste and 20-30% by weight of a hydraulic cementing material, and mixing the powder solid waste and the hydraulic cementing material to prepare a cementing material; and preparing the baking-free brickby taking the following components in percentage by weight: 20-30% of a cementing material, 20-40% of solid waste particles with the particle size of less than 5mm and 30-60% of solid waste particles with the particle size of greater than 5mm, adding water and a water reducing agent, mixing and molding. According to the method, powder solid waste granulation is used for blocking crack propagation, the mechanical property established by active solid waste powder forming can be exerted to the maximum extent, and a more practical and reliable new path is provided for powder solid waste recycling.
本发明公开了一种粉体固废造粒免烧砖及其制备方法，属于固废建材化资源利用技术领域。该制备方法包括步骤如下：按重量百分数计，取粉体固废80%~90%，水硬性胶凝材料10%~20%，加水和减水剂造粒，制得粒径1~30mm的固废颗粒；按重量百分数计，取粉体固废70%~80%和水硬性胶凝材料20%~30%，混合后，制得胶凝材料；按重量百分数计，取胶凝材料20%~30%，粒径小于5mm的固废颗粒20%~40%，粒径大于5mm的固废颗粒30%~60%，加入水和减水剂混合成型，制得免烧砖。本发明以粉体固废造粒阻隔裂缝扩展，能够最大程度发挥活性固废粉体成型所建立的力学性能，为粉体固废资源化提供了更为切实可靠的新路径。
