Utilization of Industrial By-Product (Steel Slag) as a Construction Material

S. Sharmila, M. Keerthana, S. Kiran Kumar


Construction industry is one of the largest industries with large of employment and investment. In the other hand management of industrial wastes in developing countries like India is a great challenge for the civil engineers. Utilization of industrial wastes in concrete will be a promising solution for both of the challenges mentioned. One such solution will be obtained by using steel slag in concrete. The properties of steel slag were tested. It was sieved using IS 20 mm sieve. Cubes, cylinders and prisms are casted and cured for 7 days and 28 days. Whole study was done as three trails. In first trail fine aggregate was kept constant and coarse aggregate was replaced by 40%, 50%, and 60%. In second trail coarse aggregate was kept constant and fine aggregate was replaced by 40%, 50% and 60%. In third trail both fine and coarse aggregate was replaced by 40%, 50% and 60%. It has been concluded that Compressive strength of concrete has been improved in third phase (i.e.,) 40 % replacement of natural sand and coarse aggregate with steel slag of fine and coarse aggregate respectively.  Based on the experimental results, it could be recommended that steel slag could be effectively utilized as coarse and fine aggregate in all concrete applications.
