Why is gypsum added to cement during its manufacture give reasons? When cement is mixed with water, it becomes hard over a period of time. This is called setting of cement. Gypsum is often added to Portland cement to prevent early hardening or flash setting, allowing a longer working time. Gypsum slows down the setting
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. 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.
What is Gypsum? Gypsum is a naturally occurring mineral mined from deposits formed by ancient seabeds as a raw material. Composed of calcium sulfate and water, it is used for a variety of manufacturing, industrial, and agricultural uses. Its color...

27/09/2018#0183;#32;Role of Gypsum in Cement. The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water. The process involved in hydration of cement is that, when the water is added into cement, it starts reacting with the C3A and hardens.
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.

Without gypsum, cement clinker can condense immediately by mixing with water and release heat. The major reason is that C3A in the clinker can dissolve in water quickly to generate a kind of calcium aluminate hydrate, a clotting agent, which will destroy the normal use of cement.

14/08/2019#0183;#32;The purpose of adding gypsum to cement is to increase the setting time of concrete. The percentage of gypsum in cement varies from 34%. It is added at the end of manufacturing of the cement. Simply it is a retarder. If it is not added the cement or concrete will set immediately after the addition of water. Hope u can understand.
Gypsum plaster is a 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.

Does gypsum lower the setting time of cement? When the gypsum is added in the correct amount (typically 5% by weight of cement), it is most emphatically not going to lower the setting time. It should increase it. Or it was not added to Portland ce...
