2. When desulfurization gypsum is used as a cement retarder to prepare cement, the cement has a larger specific surface area than the natural gypsum during the same grinding time. The grindability of desulfurized gypsum is better than natural gypsum, and the desulfurized gypsum itself is a fine powdery material.
Mike Howells Powdered gypsum is typically used to make plaster. Also known as Plaster-of-Paris, gypsum plaster is a building material that features similar properties to mortar or cement. It is created by heating gypsum, a soft, naturally-occurring mineral, to roughly 300 degrees Fahrenheit 150 C, and then mixing it with water.

Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 34 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.

Oct 31, 2019 The optimum gypsum usage in cement is a function of type of milling system as well as on the type of cement OPC, PPC and PSC. The optimisation should always be carried out in plant grinding system as the optimum gypsum is also a function of particle size distribution of the cements.
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. If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
Gypsum is often added to cement and concrete to slow down the drying time. Cement dries quickly and retarding that process allows workers to pour the mixture into the various forms or frames needed. The terms cement and concrete are used interchangeably, although cement is actually an ingredient of concrete.
