Although there has been many research regarding improving anti-shock performance and durability of concrete using fiber-reinforcement, there are still drawback on workability with interruption of fibers such as fiber-ball. Hence to solve this problem, in previous research, the optimum combination of fibers to improve workability of HPFRCC. In this research, based on the result of previous research, to improve the workability further, various fine aggregate contents is evaluated on workability, and the most appropriate mixing proportion is suggested.
