Why Is Gypsum Added And Ground With Clinker Ball

Apr 12, 2021

Oct 03, 2017 Grinding of the clinker is done in large tube mills which are kept cool by spraying water on them from outside. While grinding the clinker three to four per cent gypsum (Calcium sulphate) is added so as to control the setting time of cement. Finely ground cement is stored in silos from where it is drawn for packing

    The setting time of the cement is adjusted by putting more or less gypsum in with the clinker when it is being ground. The gypsum affects the reactions of the aluminate phase (C3A) in the Portland cement to moderate the setting time. Adding an excess of gypsum can produce “false set” where the gypsum itself sets quickly, before the cement does
