Gypsum Content - an overview ScienceDirect Topics

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.
