ABSTRACT:
A combination of a class C fly ash having a high analytical content of CaO, and a silica fume, with a hydraulic cement, such as Portland cement, produces concrete with alkali-silica reactive aggregate having acceptable low expansion such as by ASTM C 1260; and also produces sulphate resistance with mineral aggregates generally.
