Impact of limestone fineness on cement hydration at early ...

This study compares the influence of two limestone fineness on strength development and cement hydration. The replacement of clinker by 20% of fine limestone (d v,50 = 2 μm and SSA = 4,21 m 2 /g) gives similar strength development to PC up to 7 days. Fine limestone enhances cement hydration and offsets the dilution effect caused by the decrease of clinker amount.
