Abstract

1. A method of manufacturing hydraulic cement based on Portland clinker and residual calcium sulphate characterized in that mixing of the clinker and the residual calcium sulphate is effected : - by simply mixing said components after grinding of the clinker until the degree of fineness of the desired cement is obtained, and optionally grinding the residual calcium sulphate separately ; or - by limited co-grinding of said components, which comprises deferred introduction of the calcium sulphate in the course of grinding of the clinker alone, so as to effect co-grinding thereof for a limited period of time, said period of time being at least equal to that required to produce a homogeneous mixture but being less than the grinding time required to grind the clinker to the degree of fineness of the desired cement.
