Can bauxite residue be used in the production of

The cement sector can offer both industrially mature and industrially promising uses for bauxite residue, BR. Even if the cement sector is not panacea and most probably case specific. conditions will eventually determine a multitude of valorisation paths per refinery, it does offer a tangible paradigm. Some main points are summarised as follows:

Bauxite residue in cement and cementitious

2013-4-1  Utilisation of Bayer's process bauxite residue, BR, aka red mud, takes place in a very small fraction worldwide, most probably <5 wt.%. A success story in terms of industrial implementation is utilisation of BR as a raw material in cement production. The use of BR as a pozzolanic material has also been reported, with promising results in laboratory

Boosting the use of bauxite residue (red mud) in

2021-7-1  In the present work, we aim to use approximately 35 wt% bauxite residue in the production of Fe-rich calciumsulfoaluminate-ferrite cements (CSAF). We aim to assess the influence of the complex chemical composition of the raw meal including Fe, Ti and Na (due to the high addition of bauxite residue) on the phase assemblage and microchemistry, as well as on the resulting hydration kinetics.
