Abstract

The acoustic emission (AE) technique, one of the NDT (non-destructive method), is more effective for assessing corrosion in the concrete structures. The main objective of this study is to utilize the AE technique for assessment of pre-corroded concrete specimens under load testing. The experiments were utilized for small scales of pre-corroded specimens subjected to monotonic loading for AE signals. For the result of the experiments, the AE parameters include the AE hits, RA value, and AF of the AE data were successfully introduced to assess the flexure behavior of the pre-corroded beam specimen. The experiments conducted in this research helped to understand the flexural behavior of the pre-corroded specimen under loading test using the AE technique.
