Effect of ferrochrome slag and fly ash on the mechanical properties of concrete

Abstract

Now a day’s construction industry is focusing on various wastes from other industries to use them as substitutes for construction materials which will reduce their initial cost and impact on the environment. Use of industrial waste materials in concrete is a substitute for the shortage of natural resources. Waste disposal from steel manufacturing industries and power plants are increasing day by day and creating a lot of environmental pollution due to lack of utilizing them. There is a lot of wastes from industries like fly ash, GGBS, and slag-based compounds which can be used as replacement materials for aggregates. The present experimental investigation examines the possibility of replacing coarse aggregate with ferrochrome slag waste obtained from steel manufacturing industries and cement with fly ash obtained from power plants in concrete mix design for many construction practices. The experiments were conducted on the concrete mix in which natural coarse aggregate is replaced with ferrochrome slag to achieve optimal replacement of ferrochrome slag and the effect of fly ash along with the optimal ferrochrome slag on the mechanical properties of concrete.
