    Abstract

    Concrete paving slabs were tested to achieve the following three objectives: (1) assess the degree of freeze-thaw durability required in the various climatic regions of Canada, (2) assess the merit of standard testing methods, and (3) evaluate the adequacy of commercial products. Results indicated that: the amount of salt used for the same area at the various sites differs greatly (3 kg in Saskatoon, 277 kg in Ottawa); the moisture content, regardless of the season, is close to saturation (relative humidity 87 percent); neither the standard cyclical freezing-thawing nor the standard salt-scaling tests yield representative results; all the commercial products, with one exception, could be judged durable.
