Abstract: Two different test methods, the beam bending test according to JSCE SF-4 and a centrally loaded round panel test based on ASTM C1550 were used to characterize the toughness, or energy absorption capacity, of polymer modified, fiber reinforced high strength concrete. Two different fibers types, deformed steel fibers and synthetic fibers, were used to reinforce a high strength concrete matrix containing a polymer latex. The compressive strength of the various concrete specimens weas in the range of 70 – 80 MPa. Though there were some differences in the test results, the two methods were generally in qualitative agreement. It would appear that either method could be used to provide a reasonable characterization of the toughness of fiber reinforced concrete. However, they would not necessarily rank different fiber concretes in the same order in terms of toughness.
