Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.

Gypsum plaster should be added to water not vice-versa until a homogeneous mixture is attained. (Water gypsum ratio 70 % ) Apply Gypsum plaster on the wall and trowel the surface progressively till you attain a smooth finish. The recommended thickness of the Gypsum plaster is 10-15 mm.
Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the “setting of cement”.

No. Alkali-Resistant Cement Board Tape is specifically designed for cement board finishing and is used with a dry or thin set mortar. There are exceptions, but for the most part, durabond is used for drywall applications. For durock, a cement board, you will definitely want to use Alkali-Resistant Cement Board Tape, but with a thin set mortar.
To make a gypsum plaster, manufacturers add cross-linking chemicals to bind the mixture. Without these hardening chemicals, the gypsum paste is called drywall joint compound, or mud-- with them added, the mixture variously becomes patching compound, plaster of Paris or hot mud.
How to Apply Joint Compounds to Durock Cement Boards. Durock Cement Boards are a type of drywall reinforced with cement for a harder surface.
