. Most hydraulic structures are known as long service life structures and abrasion erosion is one of the major problems in this buildings. Former studies have focus on improving the mechanical properties of concrete. Using different additives have reported success in their concrete design mixture and fiber and pozzolan are of the additives that can improve mechanical properties of concrete. The present study is aimed to investigate the effects of adding Nano-Silica and Silica-fume treatment on the abrasion resistance of fiber concrete, containing different volume factors of hybrid steel-polypropylene fibers. For comparison, the compressive and shear strength and also abrasion resistance of plain concrete and the concrete containing hybrid fibers and pozzolans are also experimentally studied in this work. The ASTM-C1138 standard apparatus was used to measure the abrasive strength characteristics for angle speeds of 1000 and 1500 rpm. Also the Analytical model was presented for computing the abrasion erosion depth based on the effective factors herein. Based on the results, the maximum increase of compressive strength and maximum decrease of abrasion depth is obtained by adding 1% Nano-silica and 10% Silica-fume instead of cement. Also the maximum increase of compressive strength and maximum decrease of abrasion depth on fibrous concrete is obtained by adding 0.5% hybrid steel-polypropylene fiber to the concrete. Adding 0.5% hybrid steel-polypropylene fiber increase more than 60% on shear strength and decrease 13% of abrasion depth on fibrous concrete. Adding more than 1% fiber to the concrete decrease the compressive and shear strength and abrasion resistance, whereas increase the abrasion depth.
