Abstract:
Deterioration resulting from oxidation of sulphide-bearing aggregates has caused damages in many structures in North America in the last decade. In addition to petrographic analysis and other tests carried out on aggregates, attempts have been made to develop tests that evaluate the aggregates when used in cement mixtures. This presentation will cover the application of a newly developed protocol for evaluating sulfide-bearing aggregates and shed light on possible mortar tests. This session has been AIA/ICC approved for 2 CEU/PDH credits.
