Mitigating alkali aggregate reaction

摘要

This special issue of Concrete Institute of Australia journal is dedicated to mitigation of Alkali Aggregate Reaction (AAR) in concrete structures. Mitigation, depending on the concept used, can be achieved through two broad pathways; being suppression of the reaction itself, so that AAR does not develop in the concrete, and mitigation of the effects of AAR, i.e., after AAR has developed in given elements. The papers presented in this issue are concerned with the former concept, as it is economically more attractive to avoid AAR than to deal with the management of its effects.
