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”.
Cement is produced from a chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients that are carefully measured to get the right result. Often gypsum is added during the final grinding process since it helps regulate how long the concrete takes to set.

During the manufacturing of cement process, upon the cooling of clinker, a small quantity of gypsum is introduced at that time of the final grinding process. Cite 1 Recommendation
Oct 31, 2015· Why Gypsum is added to Cement? 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 of cement so that cement is adequately hardened.
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 is a mineral and is hydrated calcium sulphate 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
The cooled clinkers are finally ground in ball mills or tube mills. Also, the gypsum is added during grinding about 2-4%. The gypsum acts as a retarder and so allows the cement to mix with sand or aggregate and to be placed in position. I.e. it increases the initial setting time of cement. Storage and Packing: As cement comes out from grinding mills, it is collected in a hopper and taken in
