Studies on Repair of Reinforced Concrete Structures(II) - Their Influence on Flexural Performance -

철근콘크리트 구조물의 보수 공법연구(II) - 휨 거동 비교 -

A series of 15 reinforced concrete beams was tested to explore the effects of polymer repair on damaged beams. The key parameters for this study were the repair materials, repair methods, repair depths and repair locations. The repaired specimens failed by a typical flexural mode, showing minor interface failure. The results show that epoxy, polyester resins and latex modified cementitous mortars are effective for repairing the concrete beams. The results also show that the depth and the location of the repair do not change significantly the flexural preformance of the repaired beams.
