Use of waste gypsum to replace natural gypsum as set ...

2009-5-1  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). The amount of gypsum used in clinker varies from 3 to 5 wt%, depending on its purity (Potgieter et al., 2004).

What is the purpose of adding gypsum in cement? -

What is the purpose of adding gypsum in cement? Gypsum is a mineral and is hydrated calcium sulfate 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.

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.
