| Outline of Final Research Achievements |
In this study, the measurement condition optimized by considering the multiplicity was found in order to improve the measurement accuracy of the bond stress measurement for the reinforced concrete using an angular dispersive neutron diffraction. New monochromator system for the neutron engineering diffractometer RESA-1 in JRR-3 in Japan Atomic Energy Agency was developed to realize an accurate stress measurement based on the measurement condition optimized in this study. Furthermore, the flexural bond stress evaluation of the reinforced concrete under bending moment and the bond stress evaluation of the post-installed adhesive anchor under pull-out loading were carried out, and it was clarified that the neutron stress measurement can be useful technique in the structural engineering study for the reinforced concrete.
