Laboratory-produced high-volume fly ash blended cements: Compressive strength and resistance to the chloride-ion penetration of concrete
This paper presents data on the performance of the concrete made with high-volume fly ash (HVFA) blended cements using fly ashes from Canada and the USA. The parameters investigated included the compressive strength of concrete and its resistance to the chloride-ion penetration. Regardless of the type of the fly ash used, the concrete made with the HVFA blended cements developed higher compressive strength at all ages than that of the HVFA concrete in which unground fly ashes and laboratory-produced portland cements had been added separately at the concrete mixer. The increase in the compressive strength was more significant for the HVFA blended cements produced with the cement without a superplasticizer (SP) and made with coarse fly ash. The use of the HVFA blended cements improved the resistance of the concrete to the chloride-ion penetration, and the improvement in the resistance increased with an increase in the intergrinding time of the fly ash and the cement.
