The copper production process causes waste and by-products called waste copper slag (WCS). A considerable amount of WCS is produced globally. This research aims to utilise WCS as an alternative to natural coarse aggregate in self-compacting concrete (SCC). To achieve this goal, WCS was utilised in different percentages (0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%) as a natural coarse aggregate replacement in SCC production. Following this, the fresh, mechanical, and durability characteristics of SCCs incorporating WCS as a partial replacement of coarse aggregates were investigated in-depth. Incorporating 100% WCS as coarse aggregates in SCCs showed 27%, 29%, and 26% growth in compressive, split, and flexural strengths in 28 days, respectively. The reduction of free drying shrinkage of the mixture containing 100% WCS compared to the control mixture was approximately 36%, and the water absorption of all the specimens was less than 6%. Further, the increase in weight for the mixture containing 100% WCS as coarse aggregates was less than 15% compared to the control mixture. A cost analysis of the SCCs showed that incorporating WCS for all coarse aggregates reduced production costs by 19%. Investigating the economic index of concrete containing WCS as a coarse aggregate showed that utilising the WCS in green SCC was feasible.

铜生产过程会产生废物和副产品，称为废铜渣（WCS）。全球生产大量的WCS。这项研究旨在利用WCS作为自密实混凝土（SCC）中天然粗骨料的替代品。为了实现此目标，WCS以不同的百分比（0％，10％，20％，30％，40％，50％，60％，70％，80％，90％和100％）使用SCC生产中的骨料替代。此后，深入研究了结合WCS作为粗骨料的部分替代品的SCC的新鲜，机械和耐用性。将100％WCS作为粗骨料加入SCC中，在28天内抗压强度，劈裂强度和抗弯强度分别增加了27％，29％和26％。与对照混合物相比，含100％WCS的混合物的自由干燥收缩率降低约36％，所有样品的吸水率均低于6％。此外，与对照混合物相比，包含100％WCS作为粗骨料的混合物的重量增加小于15％。对SCC的成本分析表明，将WCS用于所有粗骨料，可将生产成本降低19％。对以WCS为粗骨料的混凝土的经济指标进行调查表明，在绿色SCC中使用WCS是可行的。对SCC的成本分析表明，将WCS用于所有粗骨料的成本降低了19％。对以WCS为粗骨料的混凝土的经济指标进行调查表明，在绿色SCC中使用WCS是可行的。对SCC的成本分析表明，将WCS用于所有粗骨料的成本降低了19％。对以WCS为粗骨料的混凝土的经济指标进行调查表明，在绿色SCC中使用WCS是可行的。
