Abstract:

Freeze-thaw resistance is a key durability factor for concrete pavements. Recommendations for the air void system parameters are normally 6 ± 1 percent total air and a spacing factor of ; < 0.20 millimeter (mm) (0.008 inch). However, it was observed that some concretes without these commonly accepted thresholds presented good freeze-thaw resistance in laboratory studies. ; This study evaluated the freeze-thaw resistance of several marginal air void mixes with two types of air-entraining admixtures, a Vinsol® resin and a synthetic admixture. To conduct the study, researchers used rapid cycles of freezing and thawing in plain water, with no deicing salts. ; For the specific materials and concrete mixture proportions used in this project, the marginal air mixes (concretes with fresh air contents of 3.5 percent or higher) presented an adequate freeze-thaw performance when Vinsol resin-based air-entraining ; admixture was used. The synthetic admixture used in this study did not show the same good performance as the Vinsol resin admixture.
