Static load and bending fatigue tests are used to compare the performance of concrete with basalt fiber of different sizes.Based on the fatigue test results,the bending fatigue life fitting curve is established and the fatigue strength of concrete is calculated.The results show that the multi-scale fiber can play a bridging role in the concrete matrix,and the average fatigue life of the concrete after toughening is increased by one order of magnitude,but the fluidity of the sample is decreased compared with that of the sample without fiber.
