Fineness Of Cement - Construction How

Fineness of Cement. One of the last steps in the manufacture of cement is the grinding of clinker mixed with gypsum. Because hydration starts at the surface of the cement particles, it is the total surface area of cement that represents the material available for hydration. Thus, the rate of hydration depends on the fineness of the.

Grinding - Mineral Processing
