EVERYTHING YOU NEED TO KNOW ABOUT THE CHEMISTRY OF KILN FEED AND CLINKER
However, the cement as yet has not been produced. If just clinker alone is ground, the final product would be an inferior, unworkable cement. To control setting time, gypsum has to be added to the clinker during the finish-grinding process. Typical portland cement contains approximately 5% of gypsum.
