Properties of Sustainable Concrete Containing Red Mud: A Review

Abstract

Concrete is an essential construction material and major component of concrete is cement. There is a huge amount of carbon dioxide emission into the atmosphere during manufacturing process of cement which has negative impact on the environment. Thus it become necessary to discover a substitute material for cement in concrete. Rapid industrialization generates a significant quantity of waste material which are causing negative effect on environment. These wastes can be a replacement for traditional material which are used in concrete like cement or fine aggregate. Red mud is waste material which generated from bauxite ore at the time of production of aluminium by the Bayer process. In this review paper, the effort is made to present the properties of concrete with red mud after studying several research papers. This paper discusses the properties of red mud concrete such as workability, compressive strength, split tensile strength, flexural strength, water absorption and modulus of elasticity. This paper shows the feasibility of partial substitution of cement in concrete by red mud. The study shows that incorporating red mud resulted increase in strengths of concrete such as compressive, split tensile and flexural strength. The water absorption of concrete decrease as increase in red mud content, it can be established that there is a possibility for using red mud in concrete as a binder ingredient for sustainable construction.

Properties of Self Compacting Concrete Containing Silica Fume as a Sustainable Alternative: A Review

“…Self-Compacting Concrete differs from normal concrete as it is at a higher end in workability and the issues of segregation and bleeding are encountered in these types of concrete" [2]. "Cement production, on the other hand, results in the release of greenhouse gases into the atmosphere" [3][4][5]. "According to studies, every ton of cement produced emits roughly half ton of carbon dioxide, which is a considerable quantity contributing in 5% of total man-made CO 2 emissions, with India accounting for nearly 7-8% of overall carbon dioxide emissions" [6,7].…”
