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

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.
