Abstract

Red mud is a byproduct produced in the process of extraction of alumina from bauxite. The process is called Bayers Process. It insoluble product and is generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure. This paper describes the characteristic properties of Red Mud and possible use as a geotechnical material. Basics properties like Specific gravity, Particle size distribution, Atter Berg’s limit, OMC and MDD are determined. Engineering properties like shear strength, permeability and CBR values are also determined in conformity with the Indian Standard Code and test results are discussed in geotechnical point of view. It revealed that the behavior of red mud is likely as clay soil with considerably high strength compared to conventional clay soil. KEY WORDS: Red mud, Bayer’s process, Bauxite residue. I
