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

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
