This study examined the mechanical properties of fiber-reinforced cementitious composites (FRCC) using hooked-shaped steel fiber (HSF) with deposited multi-walled carbon nanotubes (MWCNTs) for MWCNTs dispersion. The results showed that the fiber deposition that dispersant methods. Also, within the scope of this study, an MWCNTs incorporation ratio of 5 wt.% was found to be optimal for HSF at 1.5 vol.%, and the fiber deposition method was confirmed to have the potential to enhance MWCNTs
