    The fineness of the limestone powder in the tested range (362–812 m 2 /kg) does not seem to play an important role. The fineness of the OPC was the most important parameter during the early stage of hydration. The fineness of the fly ash became important at 28 days as fine grinding accelerated the pozzolanic reaction of the fly ash.
