Abstract

Abstract: In today's construction scenario, concrete is one of the most frequently used building material next to steel, timber and aluminum. Concrete's worldwide usage has led the researchers to improvise its properties. Several waste materials are being used with concrete either as partial replacement or replacement by the weight of cement. Red mud is one of such waste material obtained from Bauxite refining in alumina preparation by Bayer's process. This study investigates the performance of Red mud on strength and durability of concrete by conducting series of tests by substituting cement by weight with 10%, 20% and 30% of Red mud. Based on the results obtained, the strength properties of concrete increased by replacing cement with Red mud by 20% of weight of cement. In case of its durability property, water absorption percentage of the concrete replaced with 30% Red mud by weight of cement is lower than that of conventional OPC concrete. Surface resistivity value is slightly higher when compared with the conventional concrete. Higher the surface resistivity value, lower the conduction property of concrete.
