What is Cement Clinker? Composition, Types Uses Civil ...

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln. ...

What is the purpose of adding gypsum in 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.
