In order to improve mechanical properties of concrete and reduce the use of steel, in this experiment, polyacrylonitrile fiber (PAN) and polypropylene thick fiber (PPTF) were mixed to replace the use of steel fiber, and the thickness of the PAN-PPTF concrete was changed. The results showed that the compressive strength of concrete test blocks decreased with the increase of the thickness of PAN-PPTF concrete, but the split-tensile strength and bending strength of test blocks both increased. When PAN-PPTF concrete was 1/3 of the test block, the compressive strength decreased by 5.62%, but the split-tensile strength increased by 36.08%, and the bending strength increased by 38.48%.
