What is the purpose of adding gypsum in cement?

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”.

Gypsum concrete - Wikipedia

Gypsum concrete is a building material used as a floor underlayment used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling. It is a mixture of gypsum plaster, Portland cement, and sand.

Role of Gypsum in Cement and its Effects

Gypsum prevents Flash Setting of cement during manufacturing. It retards the setting time of cement. Allows a longer working time for mixing, transporting and placing. When water is mixed to cement Aluminates and sulfates get react and evolve some heat but gypsum acts as coolant and brings down the heat of hydration.

What is Gypsum Cement? (with pictures)

Sep 30, 2019· In the manufacturing of gypsum cement, raw gypsum is mined from the earth and burned at an extremely high temperature to remove all traces of water. It is then ground to a very fine powder, and mixed with alum to speed up the drying process. When water is added to this powder mixture, pure gypsum cement is produced.
