초록

연구의 촛점은 강섬유 보강 고강도콘크리트와 고장력 철근 사이의 부착 특성을 평가하였다. 강섬유 혼입률에 따른 2가지 종류의 고강도콘크리트에서 고장력 철근의 부착 성능을 평가하기 위하여 직접 부착 실험을 실시하였다. 또한 콘크리트의 압축강도의 영향을 최소로 고려하여 강섬유 혼입률에 따른 부착강도의 영향을 결정하기 위하여 상대 부착강도를 정의하였다. 부착 성능 실험 결과 강섬유의 혼입률이 증가할수록 증가하였으며 강도가 높은 콘크리트 배합에서 더 우수한 결과를 나타내었다. 콘크리트의 강도에 대한 영향을 최소로하여 강섬유 혼입률에 따른 영향을 분석하기 위한 상대부착강도 평가 결과 섬유의 사용량이 증가할수록 상대부착강도가 증가하여 섬유의 혼입률은 고강도콘크리트의 강도에 관계없이 부착강도가 증가하였다.

This study was to evaluate bond properties between high-strength steel fiber reinforced concrete and high strength steel rebar. An direct bond test were performed to evaluate the bond performance of high strength steel rebar in two types of high-strength concrete with steel fiber volume fraction (0, 20, $40kg/m^3$). Also, relative bond strength was defined to determine the effect of steel fiber volume fraction on bond strength. The bond test results showed that the bond performance of high strength steel rebar and high strength concrete tended to increase with higher compressive strength and steel fiber volume fraction. Relative bond strength which performed to analyze effect of steel fiber volume fraction showed increased relative bond strength with increased steel fiber volume fraction.
