A Comparative Study on the Flexural Behavior of Repaired RC Beams According to the Interface Bond Characteristic between Concrete and Repair material

보수재료의 계면 부착 특성에 따른 RC보의 휨거동 비교 연구

Recently, the repair materials for defected RC structures are being developed and the performance on repaired RC structures are being studied. This experiment is aimed to evaluate the flexural performance of the RC beams repaired by premix-type materials. The parameters used in this study is the repair materials, the repair length and the treatment of interface. Flexural capacity of repaired RC beams except the polymer-repaired RC beams are similar to that of the control beam. In the flexural capacity, the RC beams treated with chipping show better results than the RC beam without chipping. The various repair lengths of the repaired RC beam are not affected to the flexural capacity.
