Gypsum Content - an overview ScienceDirect Topics

Increasing the gypsum content above 2% resulted in a decrease in strength. Increasing the gypsum content increases the C/S ratio of the C-S-H formed, which corresponds to a decrease in the intrinsic strength of the C-S-H gel. This occurs due to excessive gypsum, which reacts with the C-S-H gel formed and changes its structure.
