Abstract：
Copper slag (CPS) is a large amount of waste material produced during the manufacture of copper. The disposal of this waste material becomes a problem for environmental concerns. Therefore, it is necessary to explore feasible alternate disposal options. They may also be utilized in concrete manufacturing to cut down on the usage of cement and natural aggregates. A lot of researchers focus on utilizing CPS in concrete, either as a cement replacement or as a filler material. This article aims to summarize the literature already carried out on CPS in conventional concrete to identify the influence of CPS on the fresh, hardened and durability performance of cement concrete. Results indicate that CPS improved the strength and durability performance of concrete but simultaneously decreased the slump value of concrete. Furthermore, an increase in the durability performance of concrete was also observed with CPS. However, the higher dose results declined in mechanical and durability aspects owing to a scarcity of flowability. Therefore, it is suggested to use the optimum dose of CPS. However, a different researcher recommends a different optimum dose ranging from 50 to 60% by weight of fine aggregate depending on the source of CPS. The review also recommends future researcher guidelines on CPS in concrete.
摘要：
铜渣(CPS)是铜制造过程中产生的大量废料。这种废料的处理成为环境问题。因此,有必要探索可行的替代处置方案。它们也可用于混凝土制造以减少水泥和天然骨料的使用。许多研究人员专注于在混凝土中利用CPS，作为水泥替代品或填充材料。本文旨在总结已经在常规混凝土中进行了CPS的文献，以确定CPS对新鲜混凝土的影响，水泥混凝土的硬化和耐久性能。结果表明，CPS提高了混凝土的强度和耐久性能，但同时降低了混凝土的坍落度值。此外，CPS还观察到混凝土耐久性能的提高。然而,由于缺乏流动性，较高的剂量结果在机械和耐久性方面下降。因此,建议使用CPS的最佳剂量。然而,根据CPS的来源，不同的研究人员建议使用不同的最佳剂量，范围为细骨料重量的50％至60％。该评论还建议了未来的CPS研究指南。
