An Experimental Study on the Strengths and Flexural Deformation of Steel Fiber Reinforced Concrete According to the Steel Fiber-Type

강섬유의 종류에 따른 강섬유보강 콘크리트의 강도 및 휨변형 특성에 관한 실험적 연구

This report is the results of an experimental study on the relative effectiveness of different types of steel fiber in concrete. The fibers considered in the study were straight-indent and hooked-collated with aspect ratios of about 50~100. A fiber volume of 0~2 percent was used throughout this investigation. The fresh fibrous mixes were characterized by the slump and vebe-time, and the hardened materials by their compressive and flexural load-deflection relationships. Hooked fibers were found to be more effective than straight ones in improving the strength and energy absorption of concrete.
