Abstract:By conducting carbonation tests, water permeability tests, steel bar corrosion tests, and high temperature performance tests on hooked-end steel fiber concrete, the durability performance of the unreinforced steel fiber concrete is comprehensively evaluated. The results show that the carbonation resistance of unreinforced steel fiber concrete is improved by about 41%, the permeability resistance is enhanced by adding microfiber, the resistance to steel bar corrosion is increased by 1.57~2.16 times. Unreinforced steel fiber concrete can control the effects of subway eddy currents and achieve an equilibrium in the internal temperature field at high temperatures, effectively improving durability performance.
