Gypsum is an essential additive, as it acts as a set regulator for the cement. Other additives that are commonly used in small quantities are fly ash and limestone powder. Control of temperature is essential during grinding, since high temperatures during intergrinding could cause a transformation of gypsum into hemihydrate or anhydrite, which can cause false set (upon reconversion to gypsum) during .
