Abstract:
In 2024, the International Conference on Alkali-Aggregate Reaction in concrete (ICAAR) was held in Ottawa, ON, Canada. ICAAR-2024 was the 17th international conference on the topic; this conference normally takes place every 4 years and in 2024, the 50th anniversary of the event was celebrated. After so many years of in-depth research, numerous protocols, guidelines, and standards have been produced to help avoiding, mitigating, assessing, rehabilitating, and managing concrete infrastructure affected by AAR. However, there are still plenty of doubts and unknowns on both scientific aspects and practical procedures. The purpose of this work is to highlight my personal impressions after the 17th ICAAR, pointing out some of the current challenges and research needs and opportunities on the topic.
