Before the end of the decade of 1980s red mud became a major concern in world environmental discussions. Red mud is a solid waste product of the Bayer process, the principal industrial means of refining bauxite in order to provide alumina as raw material for the electrolysis of aluminum by the Hall-Heroult Process. Red mud is composed of a mixture of solid and metallic oxide-bearing impurities and presents one of the aluminum industry’s most important disposal problems. The alumina industry is facing an important problem regarding the settling or separation of red mud during the production process as it not only affects the productivity of alumina but also its purity. Red mud cannot be disposed of easily and in most countries where red mud is produced, it is pumped into holding ponds. The utilization of red mud is of great significance from the point of view of resource conservation & sustainability of the aluminum industry.

The direction of the research undertaken to utilize red mud is based on its chemical, mineralogical and physical properties. There is an effective way of utilizing alumina red mud to make bricks. An only slight modification in the composition of red mud is required which can be done by incorporating siliceous materials and admixtures. This paper aims at studying the behavior of interlocking blocks manufactured by using red mud for different variables. In this paper, the author is attempting to summarize the potential application of red mud in the building materials industry and use the appropriate model for its utilization. The attention is to develop an extensive red mud utilization policy framework for the building materials industry in the context of India as it has great potential of reducing the cost of construction material & developing a low-cost housing technique considering the preservation of our environment.
