Abstract
Industrial wastes and by-products have been explored for many years as green construction materials. The use of some industrial wastes and by-products including ground granulated blast furnace slag, silica fume, Red mud and fly ash has already been standardized in several codes of practice as green construction materials. 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. Ferrochrome Ash (FA) is a byproduct of gas cleaning plant of Ferrochromium industry and past studies established it as a mineral admixture to cement. Due to its chemical composition, physical nature, and mechanical properties, Ferrochrome ash has recently attracted the researchers’ the review article summarizes the physical, chemical, and mechanical characteristics of Ferrochromeash. It is observed from the review of literature that concrete made with industrial by-products and waste materials by partially replacing the ingredients of concrete possess superior properties as compared to conventional concrete in terms of strength, performance and durability. The particle size distribution, the chemical composition, mineralogy, microstructure of binder particles were analysed with advanced analytical techniques such as XRF, PSA, XRD, SEM/EDS. The results of this study not only suggest the effective utilization of ferrochrome ash for the synthesis of a new class of geopolymer binders but also provide a sustainable route for the management of ferrochrome waste currently generated in various countries worldwide. This paper presents an overview of the recent advances of the use of ferrochrome ash in various civil engineering applications such as road construction, and cement and concrete industries.
