Purity of gypsum Page 1 of 2 International Cement Review

Feb 01, 2020 Generally Gypsum having purity more than 80 as CaSO4.2H2O is considered suitable for mentaining SO3. If Gypsum having very Low purity can cause high innsoluble residue in cement and decrease the strenght due to high caly content. However high purity of gypsum 88.0 is ideal.But u should count C3A in cement before deciding SO3 target. Reply
