Dehydration of natural gypsum and the consequent formation of hemihydrate and anhydrous CaSO4 exerts a significant effect on the cement's particle size distribution. This effect may be summarized in the following key points: • Increasing the amount of natural gypsum determines an almost linear increase of the cement's Blaine specific surface.

In addition to the particle size distribution of the cement, a further factor affecting the water demand is the extent of the gypsum dehydration. 70 In roller mills, the grinding temperature remains low and as a consequence most of the gypsum remains as gypsum, and results in a higher water demand. The uneven distribution of gypsum produced by ...
