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.
The two other principal technical developments, gypsum addition to control setting and the use of ball mills to grind the clinker, were also introduced at around the start of the 20th century. An entire website could easily be devoted to the history of cement, but this brief introduction may suffice to place cement in a historical context.
