Abstract:
The experiences of ihe Pennsylvania Department of Highways with air entrained concrete, in which 33!,-555 bbl of normal strength portland cement contalning Vinsol resin were used since 1940, are reported. The Pennsylvania department’s attitude on the subject of air entrainment is characterized by more concern with the particular admixture used than with the percentage of air entrainment and suck use was inspired by difficulties with finer ground cements which prompted seeking an additive to improve pavement durability.
