Prognosis of Alkali Aggregate Reaction with SEM
Alkali aggregate reaction (AAR) is known leading to great damage in concrete, both in compressive strength and in durability. In this study, a backscattered scanning electron microscopy with energy dispersive spectroscopy is adopted to diagnose AAR reaction. The results show that the type of AAR reaction and reaction products can be easily identified and the method is precise and fast.
