摘　　要：铜渣是工业废渣中常见的废料之一,因其粒度范围和结构与细骨料相似,因此是混凝土骨料良好的替代品。为研究铜渣对混凝土力学性能和耐久性的影响,本文通过室内试验,对比分析了不同铜渣含量下普通混凝土和铜渣混凝土的抗压强度、劈裂抗拉强度、抗弯测试以及耐久性的差异,并探讨了其作用机理,研究成果可为相关工程提供参考。Copper slag is one of the common wastes in industrial residue,which is a good substitute for concrete aggregates since its particle size range and structure are similar to fine aggregate.In order to study the influence of copper slag on the mechanical and durability properties of concrete,this paper compares and analyzes the differences in compressive strength,splitting tensile strength,flexural strength and durability between ordinary concrete and copper slag concrete under different copper slag contents through indoor tests,and discusses its working mechanism.The research results can provide reference for related projects.
