Abstract
Concrete structures affected by alkali–silica reaction (ASR) may continue to expand and deteriorate long after the first signs of damage become visible. However, predicting the future expansion and mechanical degradation of ASR-affected concrete under real structural restraint remains a major challenge.
This thesis investigates the diagnosis and prognosis of ASR damage in existing concrete structures. It presents a quantitative framework that combines concrete mixture reconstruction, laboratory expansion testing, alkali availability, anisotropic damage characterization and mechanical assessment to predict the future development of ASR and support long-term structural management.
