The substitution of copper slag as fine aggregate in concrete has been investigated in the past few years. This review demonstrates that copper slag is a vital and effective substitute for environmental issues and stronger and more durable construction in the future. Copper slag is a by-product of the metal smelting process that is used as an abrasive blasting grit and releases Sulphur dioxide. In place of traditional aggregate, the goal of this study is to use copper slag mix as a brand-new, cutting-edge sustainable building material. The issue of copper slag as a waste product must be addressed. This study has been undertaken to investigate the amount of copper slag used to replace sand varied from 0% to 60%, and the amounts of cement, water, and coarse aggregate remained constant. For this research M60 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0, 20%, 35%, 40%, 45%, and 60% in concrete, to examine the strength properties, compressive strength, flexural strength, and split tensile strength for curing periods of 7 and 28 days. The current study evaluates the addition of copper slag to concrete. On the compressive strength of concrete, the impact of using copper slag as a partial replacement for fine aggregate has been studied. The density of concrete increases with the increase of copper slag content. It is seen that there is almost a 3% increase in density compared with the concrete of the control mix. Accordingly, the study shows that adding around 40% copper slag in place of fine aggregate results in concrete that is stronger, more durable, and meets other requirements.
