SA HB 79:2015 PDF Download

SA HB 79:2015 is a standard that focuses on alkali aggregate reaction (AAR) in concrete structures in Australia. The purpose of this standard is to provide guidelines on minimizing the risk of damage caused by AAR and to offer recommendations for its practical management.

The standard emphasizes the importance of understanding and addressing AAR in the specification of future construction projects. It provides guidance on testing and evaluation methods, as well as mitigation measures to reduce the risk of AAR-induced damage to concrete structures.

The document acknowledges that AAR is a complex phenomenon influenced by various factors such as the type and reactivity of aggregates, curing conditions, and exposure to moisture. Based on this understanding, the standard aims to assist engineers and concrete practitioners in preventing and managing AAR through appropriate material selection, mixture design, and construction practices.
