ASSESSING ALKALI-SILICA REACTIVITY OF AGGREGATES FROM FIELD PERFORMANCE

The field performance of aggregates in concrete is considered the definitive or "last word" in assessing the potential of an aggregate to participate in deleterious alkali-silica reactivity. This places great significance on the examinations conducted to assess field performance, as well as the interpretations of the findings. Techniques for petrographic examinations are outlined and evidence of alkali-silica reaction is compared and contrasted to that of other common deterioration mechanisms affecting hydraulic cement concrete.
