Abstract

At the present time there has been a tremendous growth in demand for construction material due to rapid urbanization. Because of this the price of sand, specifically river sand is getting very high which increases the construction cost. Projects are getting stalled due to shortage of sand. The river banks are getting swallowed over the period of time due to excessive sand extraction from rivers. Moreover, the steel industry has a serious problem of proper management of waste produced in steel production process which could also result in causing serious health problems and environmental degradation. In this study, the effects of replacing fine aggregates by unprocessed steel slag and steel dust on the strength and workability of M25 grade of concrete having mix proportion of 1:1:2 with water cement ratio 0.48 by replacing sand with steel waste (slag and dust) in ratio of 10%, 20% and 30% by weight of sand is been investigated. The steel waste used as replacement for sand consist of 80% steel slag and 20% steel dust. The results obtained are analyzed and compared with a control specimen of 0% steel industry waste or standard M-25 concrete for effective study of variation of strength and workability. Eventually the study shows that there is a considerable increase in strength and decrease in workability. Concludingly steel waste can be used as a partial replacement option for sand in concrete but only up to a limited percentage of replacement.
