Internal Swelling Reactions in Concrete: Mechanisms and Condition Assessment

This looks at internal swelling reaction mechanisms in concrete such as alkali-aggregate reaction, delayed ettringite formation, and freeze-thaw cycles. It outlines qualitative and quantitative protocols for multi-level assessment, using advanced microscopic and mechanical techniques, and includes a detailed case study.

Leandro F. M. Sanchez is an associate professor in the Department of Civil Engineering at the University of Ottawa. He is the deputy chair of the RILEM TC AAR - Alkali-aggregate mitigation in concrete and the chair of ACI Committee 221 - Aggregates. He is also the chair of the 17th International Conference on Alkali-Aggregate Reaction in Concrete (ICAAR).
