The effects of grinding on the properties of Portland

2013-11-1  The limestone fillers content in cement has no real influence except at 7 days where the dry shrinkage is more substantial when the fillers content and/or the finer grinding are high. The acceleration in hydration (see previously), which induces autogenous shrinkage at early age, is probably the cause of this increase.
