Evaluation of 3D Reinforcement Corrosion Shape in Concrete Based on Observed Temperature on Concrete Surface

Abstract

The non destructive testing system of the reinforcement corrosion is employed to observe the temperature on the concrete surface. This system is useful in case that the position of the corrosion region is investigated. However, the shape of the reinforcement corrosion can not be numerically measured, even if this system is applied. Therefore, we develop the numerical shape estimation system of the reinforcement corrosion in the concrete using the temperature on the concrete surface observed by the non destructive testing system. In addition, if the corrosion partially occurs on the reinforcement bar in the concrete, it is necessary to examine the shape of the reinforcement corrosion by using the 3D model. Therefore, the numerical shape estimation system of the reinforcement corrosion is developed for the 3D model, and the results of the numerical experiment are shown in this paper.
