Solid waste-based binding agent for sintered water-permeable brick and preparation method of solid waste-based binding agent
The invention provides a solid waste-based binding agent for a sintered water-permeable brick and a preparation method of the solid waste-based binding agent. The solid waste-based binding agent is prepared from the following components in percentage by weight: 7 to 20 percent of CaO, 10 to 18 percent of Al2O3, 50 to 62 percent of SiO2, 2 to 6 percent of MgO, 1 to 5.5 percent of K2O, 1 to 4 percent of Na2O, 0.5 to 4.0 percent of Fe2O3, 0 to 4 percent of B2O3 and 0 to 0.5 percent of ReO. The obtained solid waste-based binding agent is further prepared into a water-permeable brick, the obtained water-permeable brick is good in performance, the water permeation coefficient is larger than or equal to 0.01 cm/s, the compressive strength is larger than or equal to 30 MPa, the breaking strength is larger than or equal to 4 MPa, the mass loss rate after 25 times of freezing and thawing cycles is smaller than or equal to 5%, and the compressive strength loss rate is smaller than or equal to 20%. The porosity, the aperture and the strength of the sintered water-permeable brick are effectively regulated and controlled, the production cost is reduced, effective utilization of wastes is realized, the production cost is greatly saved, and the economic and environmental benefits are improved.
本发明提供一种烧结渗水砖用固废基结合剂及其制备方法。所述固废基结合剂按重量百分比计，成分组成为：CaO7‑20％、Al2O310‑18％、SiO250‑62％、MgO2‑6％、K2O1‑5.5％、Na2O1‑4％、Fe2O30.5‑4.0％、B2O30‑4％、ReO0‑0.5％。所得固废型结合剂进一步制成渗水砖，所得渗水砖性能良好，透水系数≥0.01cm/s，抗压强度≥30MPa，抗折强度≥4MPa，25次冻融循环后质量损失率≤5％，抗压强度损失率≤20％。实现对烧结型渗水砖孔隙率、孔径和强度的有效调控，降低了生产成本，实现了废物的有效利用，大大节约生产成本，提升了经济和环境效益。
