Recently, research and development of ductile fiber reinforced cementitious composites (DFRCC) superior to existing ones are actively conducted. DFRCC is a cementitious composite material reinforced with fibers, and it represents crack dispersing properties under tensile, flexural or compressive stress. In this study, fiber reinforced mortar specimens using recycled fine aggregate were tested under compressive, split tensile, and 3-point flexural loading. To investigate applicability of DFRCC to precast piles, the experiments and finite element analyses of precast piles were also conducted. The results suggest that the use of DFRCC for the pile-tip protection of precast piles improves the bearing ductility of the tip of precast piles. The present finite element analysis was able to simulate the effect of the use of DFRCC for the pile-tip protection of precast piles.
