Abstract Continuous growth in population, and rapid industrialization resulted in increased demand for housing. Use of natural sand for concrete production has been restricted due to environmental impact. Copper slag is a waste product, which …show more content…
The scarcity of fine aggregate for the production of mortar and concrete, as partial replacement of sand by Copper Slag have been identified. Several researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine aggregates. This paper reports on some experimental investigations on the influence of partial replacement of sand by copper slag on the mechanical properties of concrete. M30 grade concrete was designed using copper slag, partially replacing the fine aggregate The fine aggregate was replaced by copper slag at various percentages ranging from 0%, 10%, 20%, 30%, 40%, 50%, 60%, 80% and 100%. The mechanical properties of concrete determined in the laboratory include compression strength, splitting tensile strength and flexural tensile strength. The influence of partial replacement of fine aggregates by copper slag on the compressive strength, split tensile strength on cylinders and flexural strength of prisms has been evaluated. The test results showed that there is a possibility of use of copper slag as fine aggregate in
