How to Work with Gypsum Based Stones - Whip Mix

Gypsums have an exact setting time. If hard stone has a setting time (final set) of e.g. 10 - 12 minutes, it can be worked on for approx. 5 minutes (approx. half the setting time). When the surface of the stone loses its shine (loss of gloss), it can still be shaped for approx. 1 minute. After this the setting time begins.

Gypsum Addition - an overview | ScienceDirect Topics

A larger fraction of SO 3 is added to cement in the form of calcium sulfate, either as gypsum, CaSO 4 2H 2 O, or anhydrite, CaSO 4. During cement grinding, a fraction of the gypsum may be decomposed to hemihydrate CaSO 4 ½H 2 O. The main role of calcium sulfate is to control cement setting, although strength may also be affected.
