  • STUDY ON BOND PERFORMANCE OF REINFORCED CONCRETE SUBJECTED TO HIGH-TEMPERATURE HISTORY AND RESTORATION BY RE-CURING USING NEUTRON DIFFRACTION

抄録

<p>In this study, The bond performance of reinforced concrete having a thermal history was evaluated using neutron diffraction. And The restoration of bond stress by re-cured for 3 days was estimated by the same method. As a result, Local restoration of bond stress was observed in specimen with a re-cured after being heated at 600°C. However, In the case of re-cured for 3 days after being heated at 600°C, Restoration of the average bond stress did not occurred. Also, When the conventional method of evaluating bond performance was applied with heated concrete, Some differences were observed between measured value.</p>
