During the ball-milling of cement clinker together with gypsum, the heat generated can be enough to cause a partial dehydration of gypsum. Bensted [11] has studied the effect of the clinker–gypsum grinding temperature on the early hydration behavior of Portland cement. It was found that samples ground.
