A REVIEW ON USE OF STEEL SLAG IN CONSTRUCTION INDUSTRY

Abstract

The present study focuses on the process of reusing or re purposing waste material into new products. It is a substitute for conventional trash management that can lesser pollution, conserve resources, and save energy. As is well known, India is currently the world’s second largest producer of steel. Iron, calcium, magnesium, silicon, and other oxides make up most of the steel slag, a solid waste product produced during the steel making process. A substantial amount of steel slag is produced as a by-product when steel is made in a submerged electric arc furnace. Researchers are interested in steel slag as a possible green and sustainable building material because of its unique chemical composition, physical qualities and mechanical characteristics. Slag from electric arc furnaces is one of the largest waste components from steel production. Because of this, fractions from the production of steel are steel slag from electric steel valorizations technology is crucial for the utilization of slag as a secondary resource in the steel industry as well as other industries like the cement or construction sectors. In the building industry, using steel slag to make bricks has been promoted. Steel slag can vary in price due to its valuable compositions and qualities, and disposing of it in an open area can lead to a number of health and environmental issues. Therefore, we will compare these characteristics and price with those cemented bricks, also referred to as interlocking bricks, in our study. The steel slag bricks' overall strength, water absorption, efflorescence, soundness, and size uniformity have also been evaluated. The natural aggregates (sand, gravel, and crushed stones) will be substituted in our study.
