This study investigated the effect of the physicochemical properties of fly ash, including the particle sizes and chemical composition of the amorphous phase, on the compressive strength of high-volume fly ash mortars in which 50 vol.% of ordinary Portland cement was replaced with fly ash. The enhancement in the compressive strength of the high-volume fly ash mortars was observed due to the pozzolanic reaction after 7 days of hydration. This was found to depend on a combination of factors, including the content of amorphous SiO2 and Al2O3, amorphous alkalinity, and surface area per volume of fly ash. (C) 2016 Elsevier Ltd.
