Structure and microstructure of gypsum and its relevance ...
Furthermore, gypsum dehydration process occurring in the Portland cement mills is worth studying (Riedmiller et al., Reference Riedmiller, Pollmann and Motzet 1998; De la Torre and Aranda, 2003a) as the different stoichiometries (CaSO 4 ⋅2H 2 O, CaSO 4 ⋅1/2H 2 O, CaSO 4) have different solubilities.
