Gypsum is a sedimentary rock having a composition of calcium sulfate Ca SO 4 2 H 2 O It is added for imparting a retarding effect in the setting of cement Without gypsum the cement would set within minutes after adding water into it It will be therefore very difficult to work with such a type of cement

Earlier a 6 mm coat of gypsum plaster termed as POP punning is usually applied on the top of cement plaster to give a smooth finish to it before painting This is a two stage process and involves various elements like sand cement and water which has to be mixed onsite

The heated air from the coolers is returned to the kilns a process that saves fuel and increases burning efficiency After the clinker is cooled cement plants grind it and mix it with small amounts of gypsum and limestone Cement is so fine that 1 pound of cement contains 150 billion grains

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement The powdered cement is then mixed with water and aggregates to form concrete that is used in construction Clinker quality depends on raw material composition which has to be closely monitored to ensure the quality of the cement Excess free lime for example results in undesirable effects such as volume

HYDROCAL White Gypsum Cement This is a good choice for mask latex molds It is harder than 1 Pottery Plaster and will hold detail longer with repeated castings A good selection for decreasing production time on masks Also works well for quick mother molds

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” If not added the cement will set immediately after mixing of water leaving no time for concrete placing

Gypsum plaster white cementing material made by partial or complete dehydration of the mineral gypsum commonly with special retarders or hardeners added Applied in a plastic state with water it sets and hardens by chemical recombination of the gypsum with water
