The axial compressive stress-strain relationship of concrete reflects its basic mechanical performance, which is important in analyzing the performance of materials, especially in the analyzing of the elastic modulus, ductility and carrying capacity. In order to study the mechanical properties of polymer-modified concrete and steel fiber reinforced polymer concrete, a comparative study of the compressive stress-strain relationship of polymer-modified concrete and steel fiber reinforced polymer concrete was carried out, the complete compressive stress-strain curves were obtained, and the influence of polymer and steel fiber on concrete elastic modulus and compressive ductility was also studied. It is demonstrated that the compressive ductility index of steel fiber reinforced polymer concrete can reach 7.39 which is greater than that of polymer-modified concrete with the same ingredients. The results also show that steel fiber reinforced polymer concrete is better than both polymer-modified concrete and steel fiber reinforced concrete.
