ALKALI-AGGREGATE REACTIVITY IN CANADA

In Canada, three types of alkali-aggregate reaction in Portland cement concrete are recognized. Each type is evaluated using different tests. Corrective measures such as the use of low-alkali cement, lower cement contents, or pozzolans are seldom used with reactive aggregates. Beneficiation or selective extraction is used with some reactive aggregates. Work is being conducted on multi-laboratory study of existing tests and new, rapid tests. (A)
