When the mineral composition of the clinker, its fineness, and its ' gypsum content ' are modified, it is possible to obtain a blended cement that has almost the same 28-day compressive strength as an ordinary Portland cement and satisfactory durability when exposed to a mild climate. However, such cement must be used with a great caution in harsh, marine, and Nordic environments. It such

31.05.2020· 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. The retardation mechanism of gypsum is: when cement is hydrated, gypsum reacts with C3A quickly to generate calcium sulfoaluminate hydrate which deposits and forms a protection film on the cement particles to hinder
