Abstract

In the current arena, infrastructure development holds the key for the development of every nation. Concrete is one of the most utilized material by the construction industry which is a homogeneous material prepared of heterogeneous materials like Cement, sand and aggregate. However rapid urbanization has created a huge demand for natural sand hence made it even more expensive. This led the researchers to find other materials which could be used as a replacement of sand whose main chemical composition is Silica (SiO2). After a great extent of research, researchers found that materials like Stone dust, Copper Slag, Coal Fly Ash, Carbonate Sand etc. having silica composition could be used as a replacement of sand. The Present experimental investigation is carried out forM20 grade of concrete mixes with partial replacement of Fine Aggregate (Sand) with Copper Slag. Compressive Strength at the ages of 7, 28 &90 days for various combinations of Copper Slag and Sand were investigated. Sand was replaced with Copper Slag by 0%, 10%, 20%, 30%, 40% and 50%.

Keywords: Copper slag, Fine aggregate, Compressive Strength, Replacement
