FOR PORTLAND-LIMESTONE CEMENT Limestone is much easier to grind than clinker. The common intergrinding of limestone and clinker in classical ball mills is there-fore producing a cement of very high surface. The higher the limestone content, the higher the negative impact of its surface on water demand and powder flowability.
