8 Factors Affecting Setting amp Hardening Of Cement

8 Factors Affecting Setting amp Hardening Of Cement

Sep 22, 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.The cost savings from replacing clinker with additives (see item 1 above) are likely to be the largest. while production costs are plant-specific, a plant producing one million tons of cement per year will produce less clinker equivalent to the amount of finish mill additives added, i.e. 5% clinker saving in this case or 50,000 tons per.
