Abstract1   재유화형 폴리머 시멘트 모르타르의 내화성능 평가 결과, 폴리머 혼입율이 증가할수록 가열 온도에 따라 잔존 압축강도가 감소하는 것으로 나타났으며, 이는 폴리머 필름의 용융으로 인한 결과로 판단된다. 또한, 혼입율이 증가할수록 폴렬현상이 빈번하게 발생하였으므로, 폴리머 시멘트 모르타르를 사용한 단면복구를 진행할 경우 상기의 내화성능을 고려한 보수재료의 선정이 이루어져야 할 것으로 판단된다.
Abstract2   In this study, the fire resistance performance of polymer cement mortars which are used as a representative repair material for section restoration, is evaluated and  residual bond strength is measured by considering unity with concrete. According to the evaluation of fire resistance performance of re-emulsification type polymer cement mortars, residual compressive strength was drastically decreased according to heating temperatures with an increase of polymer addition rate, and this seems to be attributable to the application of polymer film. In addition, an explosion phenomenon occurred frequently with an increase of addition rate, so this should be considered when selecting repair materials and processing.
