An Experimental Study on the Property of High Performance Concrete for Concrete Filled Tube with Addition Content of Steel Fiber

강섬유 첨가량에 따른 콘크리트 충전강관용 고성능 콘크리트 특성에 관한 실험적 연구

This paper presents basic study to develop high performance concrete for concrete filled tube with addition content of steel fiber. In this study, all mixtures was added to nylon fiber (1.5 kg/㎥) and steel fiber was mixed by 0, 20 and 40 kg/㎥ respectively. To evaluate the property of high performance concrete was used to various test methods which were slump flow, air content, U-box test, O-lot test and L-flow(to 300 mm, 500 mm). Also, compressive strength test was measured by ages.
