Fineness of Cement  Construction How
Apr 07, 2020 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

Feb 10, 2020 Also, the fineness of cement should not be low because this will result in a low rate of hydration and a low rate of gaining strength. Therefore it is essential to determine the specific surface (m2/kg) for cement. The specific surface of cement can be determined by sedimentation or elutriation. These methods are based on stoke's law.
