- Synopsis
- Recently, research and development of the ductile fiber reinforced cementitious composites (DFRCC) superior to the existing ones have been actively conducted. DFRCC is a cementitious composite material reinforced with fibers, and it represents crack dispersing properties under tensile, flexural or compressive stress. The use of DFRCC as an energy absorption device will be one of the applications to reduce seismic response of structure. Using DFRCC instead of concrete will also enhance the durability of RC structures. 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 finite element analyses of Precast Piles were also conducted.
