英文摘要	In the cold regions of the north China, due to special climatic and environmental factors, the degradation of concrete durability caused by freeze-thaw cycles has been a widespread concern among researchers. Freeze-thaw damage is considered to be the main form of damage that causes its durability to deteriorate. Aiming at the influence of freeze-thaw damage on the service life of concrete structures in building structures, The freeze-thaw test was carried out in this paper to study the frost resistance of the formed concrete under different fiber (steel fiber, polypropylene fiber) blending modes. The durability degradation of fiber concrete under different freeze-thaw cycles was analyzed, and its microstructure was evaluated by SEM. The study found that the frost resistance of single fiber concrete is not obvious, the frost resistance of the integral fiber concrete is greatly improved, and the layered hybrid fiber concrete has excellent frost resistance performance. In addition, based on the fatigue cumulative damage Miner theory, the reliability calculation model of freeze-thaw damage is established, which can directly reflect the relationship between the reliability of the test sample and the freeze-thaw cycle. The reliability of concrete with different fiber blending methods gradually decreases to varying degrees. This theory has good applicability in the reliability analysis of concrete freeze-thaw. © 2019 ICE Publishing: All rights reserved.
