ABSTRACT
In this study, the main purpose of using fibers is to improve the abrasion and impact resistance of concrete. Figure 3 represents the abrasion loss rate by water borne sand flow of each concrete. It can clearly be found, the fibers addition to silica fume concrete can improve the abrasion resistance. The feature points to a significant change in the abrasion behavior if fiber inclusions are added to the concrete. Because the fibers increase the

bond stress between cement matrix and aggregate, the cement matrix and aggregate aren’t be removed easily by abrade. The usage of carbon, glass and steel fibers decrease the abrasion loss rate by 14%, 10% and 39% as compared to silica fume concrete, respectively.
