| Research Abstract |
This study aimed that the evaluation of the deteriorated existing concrete surface subjected to scaling was developed. Therefore, a quantitative evaluation method for deterioration surface of RC structures was devised. The experimental results revealed that a deterioration process of scaling was depended by existence of a reinforcing bar and an area of reinforcement. Further, it was recognized that an average scaling depth and a maximum scaling depth were in proportion to each other by the measurement of scaling for RC members. In addition, it was possible to predict deterioration process of scaling by measuring the average scaling depth and the maximum scaling depth.
