摘要：The mechanical properties of concrete are reduced due to the defects of recycled aggregate itself. In this paper, the fluidity, compressive strength, splitting tensile strength, flexural strength and modulus of elasticity of recycled concrete with hybrid waste fibers were tested by changing the length combination of waste polypropylene fibers and basalt fibers. The test results show that the hybrid fibers can reduce the fluidity, compressive strength and elastic modulus of recycled concrete, and 19 mm waste polypropylene fibers and basalt fibers can significantly improve the splitting tensile strength, flexural strength, brittleness and crack resistance of recycled concrete.
