하이브리드 섬유 보강 초고성능 콘크리트의 휨 거동

초록

This study aims to investigate the flexural performance of Ultra High Performance Concrete (UHPC) reinforced with hybrid steel fibers. The flexural behaviors of various types of UHPCs were evaluated by comparing reinforcing efficiencies of single and hybrid reinforcements of straight and deformed steel fibers. Finally, several fiber compositions which provide better flexural performances than that of the commercially available UHPC were suggested.
