摘　　要：铜矿渣掺合料水泥基材料是利用铜矿渣作为胶凝材料等质量取代水泥制作而成的材料。研究了铜矿渣掺合料掺量对水泥基材料的工作性、力学性能、抗氯离子渗透性能的影响规律。结果表明,铜矿渣掺合料能改善水泥基材料工作性与抗氯离子渗透性能,降低水泥基材料的力学性能,综合确定其最佳掺量为20%左右。Copper slag admixture cement-based material is made of copper slag as cementing material instead of cement.Studies the influence of the amount of copper slag admixture on the workability,mechanical properties and chloride ion penetration resistance of cement-based materials.The results show that the copper slag admixture can improve the workability and the resistance to chloride ion penetration of cement-based materials,and reduce the mechanical properties of cement-based materials.The optimum admixture is determined to be about 20%.
