摘要

•Both HVFA-65 and HVFA-80 concretes provided enhanced durability compared to a comparable Portland cement concrete.•HVFA-65 concrete gave superior performance in sulphate media and HVFA-80 gave superior performance when subject to acid media.•XRD, TGA and NMR analysis showed evidence of gypsum formation and reduction of Calcium Hydroxide content with time.•A lower Calcium Hydroxide content in HVFA-80 compared to HVFA-65 accounts for the enhanced sulfuric acid resistance in HVFA-80 concrete.
