Environment-friendly efficient high-water-content slurry curing agent
The invention provides an environment-friendly and efficient high-water-content mud curing agent which is characterized by being prepared by mixing six solid wastes including phosphogypsum, alkali residues, coal gangue, mineral powder, steel slag powder and red mud, and the mass ratio of the phosphogypsum to the coal gangue to the alkali residues to the mineral powder to the steel slag powder to the red mud is 10-15%. The invention has the following beneficial effects: (1) dry powder addition and use methods are simple and effective; (2) cement and lime are not doped, the used specific materials comprise ardealite, alkaline residues, coal gangue, mineral powder, steel slag powder and red mud, the used materials are all solid wastes, and have the environmental protection significance of waste utilization, the purchase cost of the raw materials is lower, and the construction cost is reduced; and (3) the curing agent has better applicability to high-water-content slurry, such as river dredging soil and wall protection slurry, and is small in volume shrinkage rate and high in curing strength.
本发明提供一种环保高效的高含水率泥浆固化剂，其特征在于，由六种固体废弃物混合而成，包括磷石膏、碱渣、煤矸石、矿粉、钢渣粉、赤泥，质量配比为磷石膏10～15％，煤矸石5～25％，碱渣15～35％，矿粉25～30％，钢渣粉5～15％，赤泥10～15％。本发明具有以下有益效果：(1)干粉投加，使用方法简单有效；(2)无掺加水泥和石灰，使用的具体材料包括磷石膏、碱渣、煤矸石、矿粉、钢渣粉、赤泥，使用的材料均为固废，本身具有废物利用的环保意义，并且原料购买的费用较低，降低了工程造价；(3)对高含水泥浆，如河道疏浚土、护壁泥浆等具有较好的适用性，体积收缩率小，固化强度高。
