Red Mud (RM) is an alkaline solid waste byproduct formed when alumina is extracted from bauxite ore, mainly by Bayer's process. Around 35–40% of the ore is disposed off as alkaline RM slurry [1], [2].RM disposal is environmentally detrimental to the surrounding ground, water, and air [3].Its high pH of around 13 destroys vegetation and organic matter in …

Bauxite residue can be added to the raw mix in clinker manufacturing to replace bauxite, improving its hydraulic properties and strength. Khadilkar added: "Bauxite residue has multiple advantages in cement manufacturing, such as lower silica relative to laterite/bauxite, higher alkali content and fine particles, which reduces grinding cost.
