Concrete is one of the world’s most widely used construction material. Because of the rapid growth in technology and population in India, there is a huge demand for construction material mostly for natural sand, the excessive consumption of sand causes ecological and economical imbalance. Hence it is necessary to have alternative materials for concrete to fulfill the role of sand to achieve desired strength. Copper slag is a by-product obtained during smelting and refining of copper, many researchers have already found its potential to use copper slag as natural sand substitute. Copper slag has similar particle size characteristics seemingly to that of sand. Fine grained powder of copper slag is used as a supplementary cementing material in concrete and in cement clinker production. And it is also known that concrete is weak in tension. Weak tensile strength combined with brittle behavior result in sudden tensile failure without warning. To overcome these effects large modifications are being carried out in construction industries, i.e. usage of by-products or residues such as steel fibers, the closely spaced fibers improved toughness, tensile and flexural strength of concrete and assisted to control cracking. Hence in this study an attempt is made to carry out experimental work to improve compressive strength by replacing natural sand with copper slag and also to improve the tensile strength of concrete by adding steel fibers.
