The results of abrasion resistance test of high-performance hydraulic concretes with additions of 3 types of the polypropylene fibers are presented in the paper. The results are compared to the reference concrete without fibers. For the examination of the abrasion resistance of concretes two methods were selected: the underwater method that complies with American Standard ASTM C 1138 and the Bőhme disc method that complies with European Standard EN 13892-3. The performed tests indicated that the underwater method (ASTM C1138) may by used for evaluation of the abrasion resistance of the high-performance concretes in the case of the erosive action of waterborne rubble.

W pracy przedstawiono wyniki badań ścieralności wysokowartościowych betonów hydrotechnicznych z dodatkiem 3 rodzajów włókien polipropylenowych. Wyniki badań porównano z betonem referencyjnym bez dodatku włókien. Badania odporności na ścieranie przeprowadzono dwiema różnymi metodami: metodą podwodną wg normy amerykańskiej ASTM C 1138 i metodą z użyciem tarczy Böhmego stosowanej w Europie (wg PN-EN 13892-3). Z przeprowadzonych badań wynika, że do oceny odporności betonów wysokowartościowych na ścieranie wywołane oddziaływaniem erozyjnym rumowiska można stosować metodę podwodną wg ASTM C1138.
