However, to give an expected performance, it is important to know how the fiber will be orientated and distributed in the matrix. There are many indistinct point how fiber is oriented. This paper aims to present the influence of fiber orientation to the mechanical performance of HPFRCC. In this study, one large specimen of HPFRCC is prepared with polyvinyl alcohol (PVA) fiber. Then one large specimen is cut to small coupons and the mechanical performance of HPFRCC due to the influence of fiber is examined by using the bending test and observation of cross section by mercury lamp. From the test result, number of fiber is related to the mechanical performance closely when coupon is cut on axial direction. The number of fiber is increasing as close to the mold surface. As increased the number of fiber, the bending performance increases. On the other hand, bending performance of coupon that is cut on perpendicular direction is not related to the position of the coupons and number of fibers directly.
