Copper tailing-based ultra-high performance concrete and preparation method thereof
The invention provides copper tailing-based ultra-high performance concrete and a preparation method thereof.The copper tailing-based ultra-high performance concrete is prepared from a gelling material and aggregate, the mass ratio of the gelling material to the aggregate is 1.1: 1, and the gelling material is prepared from, by mass, 50-65% of P.O 52.5 Portland cement, 0-15% of silica fume, 5-20% of copper tailing slurry, 2.5-3.8% of a polycarboxylic acid water reducing agent and the balance of water. The ultra-high performance concrete with ultra-high performance is prepared by taking the copper tailings as a raw material, the concrete has the characteristics of good working performance, high compressive strength and the like, the fluidity reaches 260-285 mm, the 28d compressive strength reaches 121.6-129.4 MPa, and a very good solution is provided for resource utilization of the copper tailings.
本发明提供了一种铜尾矿基超高性能混凝土及其制备方法，所述铜尾矿基超高性能混凝土原料分为胶凝材料和骨料，胶凝材料与骨料的质量比为1.1：1，所述胶凝材料的原料组分及质量百分配比如下：P.O 52.5硅酸盐水泥50～65％，硅灰0～15％，铜尾矿浆料5～20％，聚羧酸减水剂2.5～3.8％，剩余为水。本发明以铜尾矿为原料，制备得到具有超高性能的超高性能混凝土，该混凝土具有工作性能好、抗压强度高等特点，流动度达到260～285mm，28d抗压强度达到121.6～129.4MPa，本发明为铜尾矿资源化利用提供了很好的解决方案。
