What is the purpose of adding gypsum in cement?

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”. If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.

Cement Milling Understanding Cement

As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4.2H 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill.

Use of waste gypsum to replace natural gypsum as set

2009-5-1 · 1.. IntroductionThe setting behaviour of cement is mainly due to the reaction of tricalcium aluminate (C 3 A), 3CaO · Al 2 O 3.The reaction of pure C 3 A with water leads to immediate stiffening of the paste, known as flash set. Thus, gypsum is added to the cement clinker during the grinding of Portland cement to retard the rapid reaction between C 3 A and water (Neville, 2002).
