 note = {application/pdf, 論文(Article), Various deterioration and damage in reinforced concrete (RC) have been reported. Since salt is one of deterioration causes of RC, monitoring and diagnosis against deterioration are key issues. Thus, development of non-destructive evaluation (NDE) technique is important to assess corrosion process. To identify the onset of corrosion and the nucleation of corrosion-induced cracking in concrete due to expansion of corrosion products, continuous acoustic emission (AE) monitoring is available. In order to clarify these phenomena, cyclic wet and dry tests are performed in a laboratory. The SiGMA (Simplified Green's functions for Moment tensor Analysis) procedure is applied to AE waveforms to identify source kinematics of micro-crack locations, types and orientations. This study shows that the onset of corrosion and the nucleation of corrosion-induced cracking in concrete are visually identified. Then, cracking mechanisms due to the expansion of corrosion products are quantitatively clarified.},
