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.
