Abstract:
Evaluating field performance history of existing concrete structures provides an opportunity for producers and specifiers to determine the potential for deleterious alkali-silica reactivity (ASR) of concrete and the aggregates it contains. However, field performance history is not typically used and the more traditional accelerated/aggressive laboratory tests such as ASTM C1260, C1567, and C1293 are chosen. This TechNote discusses the evaluation of field performance history and the benefits that it may provide.
