ALKALI SUSCEPTIBILITY OF UK AGGREGATES
The result of Concrete Prism tests to determine the alkali reactivity of UK natural aggregates is reported. Results are compared with field performance and a limit for classification as reactive aggregate is proposed. Variations on the test carried out are reported and a threshold alkali level for damaging expansion is proposed. A range of rapid tests have been evaluated and their results compared with those from the Concrete Prism. The NBRI (National Building Research Institute) and Autoclaved Microbar tests are recommended for further evaluation. (A) For the covering abstract see IRRD 871351.
