Abstract:
Discusses the freeze-thaw durability of an air-entrained concrete (water-cement ratio = 0.44, 4 percent air) in seawater for marine construction. Two laboratory procedures were used. The first procedure approximates the field freeze-thaw conditions the concrete undergoes in the tidal zone; and the second procedure was similar to the one recommended in ASTM C 666, Procedure A. The experiments were performed in fresh water and seawater. The results suggest that in the performance of concrete under arctic conditions, surface effects probably play an important role in the deteriorative mechanisms.
