wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined.

In the production stage of plaster, the raw material is gypsum (CaSO 4.2H 2 O), which, when passing through the calcination process, forms the hemihydrate, gypsum’s main constituent [2]. The hydration of gypsum occurs through the mechanism of dissolution of the hemihydrate and dihydrate precipitation.

Dehydration of natural gypsum and the consequent formation of hemihydrate and anhydrous CaSO4 exerts a significant effect on the cement’s particle size distribution. This effect may be summarized in the following key points: • Increasing the amount of natural gypsum determines an almost linear increase of the cement’s Blaine specific surface.
