Abstract

Five fly ashes with widely varying lime contents from three countries were used for 25% of the cement by mass in identical concrete mixes, including the same quantity of air-entraining agent in each case. The hardened concrete resulted in a satisfactory air-void system in terms of freezing-thawing resistance, regardless of the lime content of fly ash.
