The article presents results of laboratory tests of fiber-reinforced concrete specimens with rigid and winding fibers inside. The tests have been performed by the standard scheme of beam test for tensile bending. In order to obtain additional data about the nature of deformation of samples during loading, two pieces of glass were set into each sample. Diagrams of the stress-deformed state of beams in the coordinates load – deformation and load – time of loading are presented. A comparative plot of specimens’ deflection dependence on the kind of reinforcing fibers is shown.
