In this study, the orientation and distribution of fiber in the vertical members of cementitious materials were evaluated by using conventional and tapered nozzles. For this purpose, the specimens with ϕ 15 × 30 cm were cast to evaluate the fiber orientation and distribution coefficients on the cutting plane. The results showed that the tapered nozzle is more effective in improving the orientation and distribution of the fiber than the conventional nozzle.
