What is Cement Clinker? Composition Civil Engineering

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 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

Jul 06, 2017 The temperature of clinker is brought to 80-90 C from 1350 C. Fast cooling is very essential to get good quality clinker. If cooling is not quick, the compound stability in clinker will be adversely affected resulting in lower strength of cement after grinding. Clinker from clinker silo is transported to clinker hopper by belt conveyor.

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.
