AbstractCertain rock types, used as aggregate, react with alkalis in portland cement to produce expansion and cracking of concrete. In Canada, several investigations of field problems have indicated a much wider occurrence of the phenomenon than was formerly thought to be the case. There are at least two different types of reaction involved. Methods of determining potential alkali-expansivity of concrete aggregate have been well developed and preventive measures have been established that are being used successfully in the field. The extra cost involved is relatively small and, in terms of added life to concrete, may be considered negligible. This paper is a brief review of the present situation in Canada.
