| 要旨 | The structural performance of deteriorated RC structures in chloride-contaminated environments depends strongly on local conditions of corrosion-damage reinforcement. Corrosion-induced surface cracking is the only key visible indicator that indicates steel corrosion inside RC members. Therefore, it is crucial to study the spatial variability of steel weight loss in relation to corrosion cracking. This paper demonstrates applications of X-ray techniques and digital image processing to continuously observe the spatial variation of steel weight loss and its relationship with surface crack widths. |
