Abstract

In this study, I examined hardening and non-hardening of the DFRCC (Ductile Fiber Reinforced Cementitious Composites) according to sand-aggregate ratio and the diameter of PVA fiber to develope PVA fiber reinforced concrete with the feature of DFRCC. As a result of this study, the fresh properties of DFRC is similar regardless of sand-aggregate ratio. The bending stress of DFRC also increased as the sand-aggregate ratio increased. And the bending stress-displacement was the most stable when the PVA $100{\mu}m$ was used regardless of sand-aggregate ratio.
