(57) The present invention pertains to a method for manufacturing cement, wherein the gypsum is first calcined separately before being inter-grinded with the clinker so as to minimize the release of water of crystallization of during the inter-grinding stage. The method produces cement of high strength at all ages, better rheology, enables higher use of fly ash, and reduces CO₂ emission during manufacturing.
