UTILIZATION OF BAUXITE RESIDUE IN SELF-COMPACTING CONCRETE AND EVALUATE RHEOLOGICAL BEHAVIOR AND MECHANICAL CHARACTERISTICS

This thesis aims to investigate the potential utilization of bauxite residue, by-product of aluminum production, in self-compacting concrete (SCC) and evaluate its impact on the rheological behavior and hardened state characteristics of the resulting concrete. Bauxite residue is a red mud waste generated during the extraction of alumina from bauxite ore. Finding sustainable solutions for its disposal or reuse is crucial for environmental and economic reasons. The research methodology involves laboratory experiments to determine the optimal proportion of bauxite residue in SCC mixtures. The rheological properties of fresh concrete, such as slump flow, flow time, and passing ability, will be assessed using standard tests. Additionally, the effects of bauxite residue on key mechanical properties of hardened concrete, including compressive strength, flexural strength, and durability, will be examined. It is reveled from the result that as the red mud percentage increases workability also increases but mechanical properties increases upto 30 percentage of red mud above 30% it get decreases.
