The waste materials of various metal industries are well established as raw materials of concrete. But the ferrochrome industry’s waste materials are falling behind in this area due to a lack of knowledge. A dust waste herein named ferrochrome ash (FCA) and a solid waste herein named air-cooled ferrochrome slag (ACFS) are two such materials from the chrome-producing industry that possess good engineering properties. ACFS is hardly used while FCA is thrown off and that pollutes the environment. This paper investigates the impact of FCA as an alternative binder and ACFS as a substitute for coarse aggregate on some of the properties of normal and structural concrete. The mechanical properties and microstructure of concrete made using 40 % FCA as a binder and 100 % ACFS as coarse aggregate was noted as comparable to regular concrete. The load caring capacity, failure pattern, crack pattern and ductile behavior of reinforced cement concrete (RCC) beams that contained 40 % of FCA and 100 % of ACFS were observed higher than those of regular RCC beams. The inclusion of 40 % of FCA and 100 % of ACFS enhanced the first crack resistance, load caring capacity and deflection of beams 75, 25 and 36 % in comparison to that of normal concrete beams.
