Abstract:Concretes containing fly ash were evaluated to establish the effect of the fly ash on freeze-thaw resistance, resistance to deicer scaling, and chloride ion penetration. The effects of low temperature curing and moisture availability during curing were also evaluated. These tests indicated that the freeze-thaw resistance of air-entrained concrete was reduced by the use of certain fly ashes when cured at low temperature. For other conditions there was no significant influence of fly ash . Deicer scaling resistance tests showed that air-entrained concrete without fly ash generally performed somewhat better than concrete with fly ash, regardless of the type of curing provided. Air-entrained concretes made with some fly ashes were as resistant to chloride ion penetration as air-entrained concrete without fly ash. The class of fly ash did not significantly influence the degree of chloride ion penetration.
