Recycling and potential utilization of red mud (Bauxite Residue) for construction industry applications

Abstract

Red mud (RM, a Bauxite Residue) is the huge waste materials generated during the alumina production followed by the Bayer Process, which processed about 1.25 – 1.5 ton from per tons of alumina production. The disposal of this waste materials is a serious issue as increasing the demand for aluminium with time. Whereas extensive research and developmental activities have been done approximately last two decades and further going on around the world to find an effective route to bulk utilization of bauxite residue (Red mud).Which, include in form of various products, processes, and technologies development with directly & indirectly consumption of red mud. Present researches worked on have been a number of potential uses to the utilization of this industrial waste. Hence the present article attempts to review the quantity, characteristics, recycling, and potential utilization of red mud (bauxite residue) especially for construction industry applications with specific reference to the product, processes, and technologies developed in India.
