Solid waste-based baking-free environment-friendly hollow brick and preparation method thereof
The invention relates to a solid waste-based baking-free environment-friendly hollow brick and a preparation method thereof, and belongs to the field of solid waste utilization environmental protection and the field of hollow bricks. Red mud, mineral powder, industrial by-product gypsum, fly ash, silica fume, aluminum ash, carbide slag, wastewater and other solid wastes and waste liquids are usedas main raw materials. The hollow brick comprises the raw materials in parts by mass: 35-50% of red mud, 30-45% of mineral powder, 10-20% of industrial by-product gypsum, 5-15% of a reinforcing agent,0.5-3% of a cementing agent and the balance of sewage or wastewater, wherein the reinforcing agent is prepared by mixing 15-23% of silica fume, 10-25% of aluminum ash, 20-30% of fly ash, 15-30% of carbide slag, 5-10% of zeolite powder and 5-15% of asphalt. Large-scale resource utilization of solid waste is achieved, the occupied area of the solid waste is reduced, environmental pollution is reduced, no natural mineral resources are consumed during preparation, multiple solid waste and waste liquid are used as main raw materials of the baking-free hollow brick, and the product has the advantages of high strength, low cost, environmental protection, energy conservation, simple and convenient process and easiness in popularization and application.
本发明涉及一种固废基免烧环保空心砖及其制备方法,属于固废利用环保领域及空心砖领域。利用赤泥、矿粉、工业副产石膏、粉煤灰、硅灰、铝灰、电石渣及废水等多种固废及废液作为主要原材料,其原料以质量分数计:赤泥35‑50%、矿粉30‑45%、工业副产石膏10‑20%、增强剂5‑15%、胶结剂0.5‑3%、余量为污水或废水,其中增强剂由硅灰15‑23%、铝灰10‑25%、粉煤灰20‑30%、电石渣15‑30%、沸石粉5‑10%、沥青5‑15%混合制备而成,实现了固体废弃物的大规模资源化利用,减少其占地,减少环境污染,且制备时不消耗任何天然矿产资源,本发明利用多固废及废液作为免烧空心砖的主要原料,产品具有高强度性能,成本低,环保节能,工艺简便,易于推广使用。
