Tests on concrete in the laboratory indied that, apart from the cement's limestone content, only the w/cratio is definitive for the durability of concretes. Even concretes based on blended CEM II/B cements (using CEM I R as the initial cement) containing 24 % limestone by mass exhibited high internal and external frost resistance (CDF/CIF and cube test).

What is the purpose of adding gypsum in cement?
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. 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 [.]
