Abstract:
Describes an experimental investigation into the strength development of CSA Types 10 and 30 (ASTM Types I and III) cement concretes and the durability of CSA Type 30 cement concretes, cast and cured at 0 C in seawater relative to conventionally cast and cured concretes. All concretes incorporated air-entraining admixtures and had plastic air contents of between 4 and 6 percent. Strength development of all concretes with temperature is dependent upon the water-cementitious ratio. Low-temperature casting and curing is not necessarily detrimental to the strength development of low water-cement ratio concretes. The resistance to freezing and thawing of air-entrained Type 30 cement concretes of water-cement ratios below 0.50 is excellent regardless of casting and curing temperature.
