Red mud is disposed as dry or semi dry material in red mud pond or bauxite mines. Achilleopoulos, 1995 and S.E. Hitherto, the relatively high per cent of soda in the bauxite waste red mud, has rendered the latter an unsuitable material for making construction bricks. In this paper characterization of red mud as a controlled low strength material (CLSM) is discussed with red mud as a base material and crusher dust or quarry dust, phosphogypsum and fly ash as other mineral admixtures. 2014-01-18T08:12:13Z Red mud is an industrial waste which is being generated by Bayer process of alumina production. China has a target to recycle 10% of all of its red mud, and Chalco has already introduced several solutions to recover iron and rare earth metals from red mud waste, so the residues can be used for steel and concrete production. The residual red mud from the above, free from sodium, is used for the production of construction bricks. It is generally dumped near the plant in a pond without any usage, occupying costly land. Many researches are still being carried out on the neutralisation of red mud in various ways. Red mud solids contain nearly 400g/L of water content, and this is the main drawback of red mud to use as raw material in the cement manufacturing process. Red Mud is a waste generated by the aluminum industry (an average of ...
