Influence of Copperslag in Concrete as Partial Replacement for Fine Aggregate

Concrete is the widely used construction material. In which fine aggregate is one of the important constituents. An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of concrete. Various concrete mixtures were prepared for M20 and M40 grade with different proportions of copperslag ranging from 0% (for the control mixture), 20%, 40%, 60%, 80%, and 100% as fine aggregate replacement. Hardened concrete tests such as compressive strength, split tensile strength for M20 and M40 grade concrete is tested and the mechanical properties of the conventional concrete is compared with copperslag concrete. The M20 and M40grade results are compared and variation in strength properties between the grades is to be examined and it is recommended up to a 40% replacement of for fine aggregate obtain a concrete with good strength and also grade wise same strength only obtained.
