How Cement And Concrete are Made

This results in the production of cement clinker, an intermediate product in the manufacture of cement. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat the kiln account for about 40% of cement

Gypsum is added to cooled clinker during cement manufacture:

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.

Difference Between Clinker and Cement

Oct 23, 2011Clinker is a component in cement. It is the active binding component in cement. Therefore, the key difference between clinker and cement is that clinker appears as marble-like nodules, whereas cement is a very fine powder. Moreover, particles in clinker size are in the range of 3 millimetres to 25 millimetres in diameter while in cement
