Abstract

Abstract

In order to enhance the fracture properties of rubber concrete, a three-point bending fracture test was conducted to study the impact of steel fiber-glass fibers on the fracture properties of rubber concrete and its strengthening mechanism. The findings indicated that the addition of rubber powder to concrete might reduce its flexural performance, but it had a positive effect on enhancing the toughness and deformation resistance of concrete. The hybrid fiber composed of steel fibers and glass fibers had a substantial positive impact on the fracture properties of rubber concrete. When the total amount of hybrid fibers was 8% and the ratio of steel fiber to glass fiber was 3:1, the flexural strength of the rubber concrete containing hybrid fibers reached 7.87 MPa, with a fracture energy of 4 681.60 J/m². Based on the analysis of the double-K fracture model, it was evident that the hybrid fibers greatly enhanced the fracture toughness of rubber concrete, with the most significant improvement observed when the total amount of hybrid fibers exceeded 6%. Additionally, the multi-scale synergy of hybrid fibers enhanced the stress-strain performance of rubber concrete, resulting in improved load resistance and toughness.
