Even if this work is still in progress, we can make a reliable hypothesis about the pre-hydration of clinker during grinding process, which is deeply influenced by the presence of the active ...
Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter - grinding in mills.

This hydration product does not bridge the water-filled gaps between particles of clinker, and the paste becomes only slightly stiffer due to initial hydration during the early period. 74 Two cements produced from the same clinker to two different specific surface areas, show very different levels of water demands and setting times.
The chemical grinding stabilizers that are linked up to the surface groups of cement particles resulting from the clinker grinding process participate in the hydration process. The rate of hydration is one of the key variables in the application of grinding additives in the cement industry. 3. Experimental 3.1.
Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
