Alkali-Aggregate reaction is a an umbrella term for two types of premature concrete deterioration: alkali-silica reaction (most common) and alkali-carbonate reaction (less common). These forms of deterioration encompass a chemical reaction between CERTAIN aggregate types and the host cement paste, most importantly the internal pore solution in concrete. AAR has been studied since the mid 1930s after the discovery of alkali-silica reaction (ASR) by Thomas Stanton of the California Division of Highways. A conference series devoted to understanding reaction mechanisms, testing methods, prediction, diagnosis and repair has been active since 1974 with a total of 14 conferences held to date. This website provides the first known web presence to consolidate and make available all of the previous ICAAR Conference Proceedings in electronic format.
The Organizing Committee is closely following the situation of the COVID-19 pandemic. Currently, the conference is planned to be held in next October; however, due to the rapid evolving of this outbreak, we will reevaluate the scheduling in May. Any changes will be reported promptly. Together we will overcome this difficult and challenging moment and make the world a better place.
