- Red mud (Bauxite residue) is an industrial by-product produced in Bayer's process of production of alumina. An inventory of 3 Billion tons of high alkaline red mud is awaiting in stock-pilling yards for its bulk utilization at global level. Annual generation of 120 MTPA of red mud is putting an additional burden on the storage yards. Concrete is the largest consumable on the earth, next to water. Consumption of concrete has already crossed the mark of 20 Billion tons per annum, globally. Aggregates comprise 60% to 80% of concrete composite volume. The available sources of natural aggregates and sand are getting exhausted because of their excessive exploitation. This has caused in increasing the further exploitation of natural resources. Hence there is an urgent need to explore a substitute material for fine aggregates in concrete. An attempt is made here to substitute Crushed fine aggregate in concrete partially with raw red mud with 0 (control mix), 50, 100, 150 and 200 kg per cubic meter of concrete .Composite of high fly ash content (50% of cementitious mass) and red mud in concrete is tested for compressive strength, flexural strength, water-binder ratio and chloride permeability.
