In this study, we conducted basic research to evaluate the long-term adhesion characteristics of post-installed anchors by using the neutron beam from JRR-3 in the future. The experiments were carried out TNRF and RESA in JRR-3. In the cross-sectional CT image near the center of the concrete, multiple holes artificially created in the concrete inside the iron can with an inner diameter of about 60 mm were clearly photographed. As a result of comparing the dimensions with the actual measurement and the image, it was confirmed that the values were almost the same, and the tip of the hole could be observed with high accuracy.

In this study, it was conducted to evaluate the long-term adhesion characteristics of post-installed anchors using neutrons, which have extremely high penetrating power for materials. In CT measurement, it was clarified that the observation inside the reinforced concrete of about 60 mm can be evaluated with the spatial resolution of about 0.2 mm. On the other hand, since the strain distribution under loading did not show a monotonous change in the strain distribution of the anchor, it was clarified that there are some problems.
