Alkali fusion of bauxite refining residue (red mud-RM) to produce low carbon cements

SN Applied Sciences, 2023
This paper creates hydraulic binders using waste and a low energy input. Cements are produced with a bauxite refining residue (red mud-RM), blended with limestone and lime, and fused at temperatures from 600 to 1200 °C.

Calcium Silicates as Lime Substitute

Water Science and Technology, 1993
An experimental study has been carried out of the removal of iron from solutions of ferric chloride by lime, β-dicalcium silicate (C2S) and α-monocalcium silicate (CS) and of the treatment of the resulting sludge. C2S promoted the flocculation of iron precipitates to achieve higher settling, thickening and dewatering rates.
