Tungsten tailing-based composite admixture and preparation method thereof
The invention provides a tungsten tailing-based composite admixture and a preparation method thereof. The tungsten tailing-based composite admixture is prepared from the following raw materials in parts by weight: 55 to 65 parts of tungsten tailings, 25 to 35 parts of alkaline blast furnace slag, 2.5 to 3.5 parts of lead-zinc slag, 2.5 to 3.5 parts of pyrite slag, 3.5 to 4.5 parts of desulfurized gypsum, 0.06 to 0.10 part of a grinding aid and 0.08 to 0.16 part of an alkaline activator. The activity index of the tungsten tailing-based composite admixture is not lower than that of S95-grade mineral powder, and the tungsten tailing-based composite admixture can be used for partially replacing the S95-grade mineral powder in concrete, improving the workability of the concrete and improving the compressive strength, durability and volume stability of the concrete, can be used for partially replacing a cement admixture in a cement raw material, and can be used for reducing the cost. The comprehensive mechanical property of the cement is improved and the production cost of the cement is reduced.
本发明提供一种钨尾矿基复合掺合料及其制备方法。本发明所述钨尾矿基复合掺合料按重量份数由以下原料制成：钨尾矿55～65份，碱性高炉矿渣25～35份，铅锌渣2.5～3.5份，硫铁矿渣2.5～3.5份，脱硫石膏3.5～4.5份，助磨剂0.06～0.10份，碱性激发剂0.08～0.16份。本发明的钨尾矿基复合掺合料的活性指数不低于S95级矿粉，其可用于部分替代混凝土中S95级矿粉，改善混凝土的和易性、提高混凝土的抗压强度、耐久性和体积稳定性，其可用于部分替代水泥原料中的水泥混合材，改善水泥的综合力学性能、降低水泥的生产成本。
