Review of Utilization of Steel Slag in Flexible Pavement

Abstract

In India the total production of Steel slag is nearly 40.5 million tons of slag between 2017 and 2018 (Indian mineral Yearbook, May 2019). In India right now, due to restricted links of usage, a high amount of iron and Steel slag is deposited in the yards of every manufacturing facility, occupying key agricultural land and causing severe pollution to the entire ecosystem. Slag usage is a cost
effective solution to these issues. Characterization in terms of both chemical and physical properties of Steel slag is an important aspect. As a road aggregate, recycled raw materials are used in flexible and concrete pavement, cement and concrete additive, soil stabilizer, and building materials, among other things. This report examines Steel slag use patterns as well as the possibility for large scale Steel slag use.
