In particular, Portland limestone cement (PLC) when co-ground in a ball mill has the tendency to be 'sticky' (see Table 1). Consolidation over time and/or a vibration and rocking motion heighten the issue. Powerful grinding aids avoid this stickiness. They broaden the interfacial gap between the limestone particles and thereby boost the

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.
