Mar 26 2015 The change is that the specification adds up to 5 limestone The biggest difference in production is that the limestone is added to the clinker blend before grinding Because the limestone is softer than the clinker it will grind preferentially resulting in a cement with a better particle size distribution with less energy The limestone also.Effect leading to a chemical activation of the cement hydration it is now generally accepted that the main effect of the limestone powder is of physical nature (Tsivilis et al 1999) In addition to cement limestone particles modify the grain size distribution The final effect depends on the fineness and the amount of powder.
