Sustainable industrial development causes accumulation of heaps of waste disturbing the natural mechanism the waste can be sometime best alternative for conventional; material like red mud. Red mud is industrial waste obtained as by product from Bayer method of alluminium extraction in this process, alkaline digestion of 2.5 T of bauxite affords alumina & 105 T of red mud. The average 4 million tones of red mud produces per annum, this amount composed of Fe & Ti oxides behaving as chemically inert material with variable percentage of nominal SiO2, Al2O3 & Na2O3 which are partly present in cement. This paper covers significance of red mud over Portland cement by partial replacement of cement up to certain extent.
