On behalf of the Organizing Committee, it is my great pleasure to welcome you to the 18th International Conference on Alkali-Aggregate Reaction (ICAAR).

Since its inception, ICAAR has brought together researchers, practitioners, and experts from around the world to share the latest developments, research findings, and practical experiences in the field of alkali-aggregate reactions and the durability of concrete structures. The 18th edition of this prestigious conference continues this tradition, offering a platform for fruitful scientific exchange, interdisciplinary collaboration, and the strengthening of our global professional community.

We are honored to host ICAAR 2028 in Argentina, a country with a rich cultural heritage, a strong engineering tradition, and a deep commitment to advancing knowledge in civil infrastructure and materials science.

We look forward to welcoming you to Argentina for an engaging and memorable ICAAR 2028. Your participation will be essential in making this event a success, and we are committed to providing an inclusive and stimulating environment for all attendees.

Warm regards,

Silvina A. Marfil

Chair, 18th ICAAR
