PROCÉDÉ DE FABRICATION DE CIMENT À PARTIR D'UNE MATIÈRE PREMIÈRE ALUMINOSILICATE
A method for manufacturing cement may include: supplying at least one etching effluent of a substrate based on silicon including a silicate of an alkali metal, M, having formula SiO2:M2O, and having a molar ratio SiO2/M2O greater than or equal to 0.8; supplying an aluminosilicate raw material, and mixing the aluminosilicate raw material with the etching effluent having a molar ratio SiO2/M2O greater than or equal to 0.8. The silicate solution of alkali metal may be recovered with an existing silicon industrial process, implementing a silicon etching. The environmental impact of the method of manufacturing cement may therefore be reduced.
