In this research, five types of polymer repair materials were selected for investigation of
the influence of sample shape, deformation rate and test temperature on the mechanical properties
determined with an uniaxial tensile test. The results showed the clear effect of measurement
conditions on tensile strength, elongation and modulus of elasticity. The highest tensile strength and
modulus of elasticity were exhibited by epoxy resin for the filling of concrete cracks, which
achieved 1% elongation. The lowest coefficient of dispersion characterized the results of tensile test
carried out using dumbbell samples at a deformation rate of 50 mm/min. The effect of temperature
varied with the material type.
