AbstractIn northern latitudes frost action is undoubtedly the main cause of concrete deterioration. In spite of considerable improvement in building practices the consequences of freezing and thawing are still of great concern, and at times the situation becomes serious. For example, the adoption, some years ago, of the "bare pavement" policy by most highway authorities has led to deterioration of bridges, highways and sidewalks through the use of deicing salts in vast quantities. Another difficulty is the marginal quality aggregates that have come into use in some regions after frost resistant supplies have been exhausted. In the present review some aspects of the mechanism of frost action will be discussed.
