Abstract

In this paper, a material design concept based on Hybrid Fiber Reinforced Cement-based Composites (HFRCC) is applied to Ultra High Performance Concrete (UHPC) so that a multi-level-reinforcement system for cracking will enhance the peak stress after crack initiation (i.e. tensile strength) and tensile strain capacity (i.e. strain at the peak stress, or ductility). UHP-HFRCC is created by means of the multi-level-reinforcement system, in which micro-fibers and macro-fibers are blended and work together for preventing crack extension in UHPC. The aim of this research is to investigate the effect of blending two different fibers in UHP-HFRCC on tensile strength and tensile strain capacity. Lastly, all results are compared with previous ones reported by other researchers to reveal the present results far exceed previous ones.
