The Effect of Bayer Red Mud Blending on the Mechanical Properties of Alkali-Activated Slag-Red Mud and the Mechanism

open access: yesApplied Sciences, 2022
In this paper, Bayer red mud and ground granulated blast furnace slag were formed into three different ratios (7:3, 5:5 and 3:7) of alkali-activated cementitious materials (AASR) using a water glass solution as the alkali activator.

Electrokinetic of red mud

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract Red mud - a bauxite residue, is a by-product of the Bayer Process for refining bauxite to alumina. Red mud is highly alkaline, due to the sodium hydroxide utilization to purify bauxite from silicate and other impurities. In order to produce one ton of aluminium, it will be yielded 0.8 to 1.5 tons of red mud is produced as by ...

A STUDY ON THE CHARACTERIZATION OF RED MUD [PDF]

open access: yesInternational Journal on Applied Bio-Engineering, 2014
Red Mud (RM) is a solid waste product obtained from aluminum industries via Bayer’s process. India is one of the largest producers of RM producing around 4 million tons annually. Its disposal is one of the major concerns as it is highly alkaline in nature and is a potential threat to air, water and land.
