The aim of the article was a comparative analysis of concrete strenght with the addition of polymer fibers subjected to three testmethods: the uniaxial tensile test, the three-point bending test, and the Montevideo splitting tensile test. One mix without fibers and five fiber reinforced concrete mixes were made with 2 or 3 kg/m3 of polymer fibers of different geometry and form. It was found that the addition of fibers did not significantly affect the maximum compressive, uniaxial tensile, flexural, and splitting tensile strength of concrete. On the other hand, residual forces and strengths, fracture energy, and ductility of concrete were significantly improved. The calculated load correlation coefficient (kTRMV = 1.5) allowed the correlation of the results of the Montevideo splitting tensile test with the three-point bending test for a crackmouth opening displacement greater than 1mm.Overall, the Montevideo splitting test may be a simpler and more compact test method compared to the three-point bending test.
