Gypsumis a mineral and is hydrated calcium sulfate inchemicalform.Gypsumplays a very important role in controlling the rate of hardening of thecement. During thecementmanufacturing process, upon the cooling of clinker, a small amount ofgypsumis introduced during the final grinding process.

Tests onconcretein the laboratory indicated that, apart from thecement’s limestone content, only the w/c-ratio is definitive for the durability of concretes. Even concretes based on blended CEM II/B cements (using CEM I 52.5 R as the initialcement) containing 24 % limestone by mass exhibited high internal and external frost resistance ...
