Freeze/Thaw durability of concrete with fly ash
Paper in proceedings, 2011

This paper presents results from a study of frost resistance of air entrained concrete with additions of fly ash. In this study, concrete with different additions of fly ash were cured at different ages and elevated temperature prior to the standard frost scaling test. The equivalent water-binder ratio was fixed at 0.45, with efficiency factors of either 0.4 or 1.0. The results show that properly air entrained concrete with fly ash achieved a frost resistance similar or even better than that of Portland cement concrete. Curing for longer ages or at elevated temperature did not improve the freeze/thaw durability.
