A Comparative Analysis by Experimental Investigations on Concrete using Red-Mud Waste Material : A Review

Abstract

In recent years, there has been a rise in the production of red mud due to a wider increase in the aluminum industry. For each tonne of alumina, typically 0.8 to 1.5 tones of RM can be generated. The annual production of RM, which is produced globally is 1.7 billion tones because of the aluminum industry's explosive growth. RM typically has a pH between 10.5 and 12.5, caused by the hydroxide (NaOH) added during the production of aluminum. The primary objective of the research is based to conduct experimental analysis on replacing cement used in concrete with red mud in different proportions namely 5%, 10%, 15%, and 20%. As stated before, the objective stated the different applications for using red mud in concrete. The concrete cubes and beam were cured and cast where the red soil was added to the samples were analyzed for slump cone test, compressive strength and rebound hammer test. Considering a range of actual grade levels. The physical characteristics of concrete that altered after red mud was applied will be supported by the evidence from this experiment.
