Anhydrite gypsum is the more concentrated version of calcium sulfate. Gypsum is a fast-release material, anhydrite gypsum a slower-release product which stays in the root zone longer making it available for plant uptake. The true cost of any particular calcium sulfate application may, ultimately, depend on its shipping cost.
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.

While both gypsum and anhydrite are basically calcium sulfate, the presence or absence of water molecules makes a big difference in their physical properties. At Mohs 1.5-2.0, gypsum is much softer than anhydrite (Mohs 3.0-3.5). The reason is that gypsum's attached water molecules increase the distance between its calcium ions and sulfate ...
