  • 8 FACTORS AFFECTING SETTING HARDENING OF CEMENT

    Sep 22 2016 · If the cement is too fine its shrinkage is large in the hardening process. Thus the finer the cement is ground the more energy will lose and the higher the cost will be. Usually the grain size of the cement particles is within 7-200pm (0.007-0.2mm). (4) The Impact of Curing Conditions
