Digital Image Correlation Analysis of Corrosion Crack Behavior in a Reinforced Concrete Member

Abstract:

The corrosion of the internal steel bars of reinforced concrete structures is still a maintenance problem. This study aims to detect corrosion cracks in covered concrete by DIC. We proposed a new test specimen and method of electrolytic corrosion testing suitable for tracking corrosion cracks by DIC (Digital Image Correlation Analysis), and succeeded in understanding the crack initiation behavior of single and double bar specimens.
