Abstract:
Describes preliminary studies . and current practice in the northeastern states in the reduction of frost action on concrete paving and other projects (roads, streets, airport pavements and hangars, bridges, and buildings); mix proportioning, methods of determining air content, and field control. Specifications tend to limit air content to 3 to 6 percent rather than fix amount of air-entraining agent used.
