The construction industry produces 5-7% of all CO 2 emissions and is the second-highest emitter of all industrial carbon dioxide. Reusing industrial waste and by-products in cementitious materials has found to enhance properties and reduce the carbon footprint. Red mud is one such byproduct generated in large quantities during the manufacturing of alumina. Red mud’s utilization in the construction industry can also address the challenge of increasing red mud reserves, posing a threat to the environment. The studies carried out by various authors suggest that red mud could successfully be incorporated in concrete and mortar. The extent of incorporation of red mud in the material can be decided based on the required application and properties. This paper presents a comprehensive review of red mud’s effect on the rheological and fresh properties of concrete and mortar which are crucial for their constructability.
