钢纤维混凝土因其优异的力学性能在工程实践中得到广泛应用。然而，与其他类型纤维相比，钢纤维在腐蚀性环境中易发生锈蚀，导致混凝土力学性能和耐久性的退化。从钢纤维的锈蚀机理、影响因素及其对混凝土力学性能和耐久性能的影响等方面，系统总结了国内外关于锈蚀钢纤维混凝土的研究进展。已有研究表明，钢纤维的耐腐蚀性能与混凝土的水灰比、纤维种类、混凝土的开裂情况以及外界侵蚀环境等有关。在未开裂的混凝土中，钢纤维仅在表层约5 mm内发生锈蚀。随着锈蚀程度的加深，钢纤维强度逐渐下降，锈蚀产物对孔隙的填充和挤压在不同时期发挥不同的主导作用，导致钢纤维与水泥基体间黏结性能的退化，影响了钢纤维混凝土的力学性能。目前，大部分研究均未考虑钢纤维锈蚀对钢纤维混凝土强度的影响，尚未建立钢纤维锈蚀与混凝土性能退化之间的定量关系。最后，结合现有研究成果，讨论了钢纤维锈蚀研究中存在的问题，并对未来研究方向进行了展望。

Steel fiber reinforced concrete has been widely used in engineering practice due to its superior mechanical properties. However， unlike other fibers， steel fibers are susceptible to corrosion in corrosive environments. This paper systematically reviews the research progress and key findings on the corrosion of steel fiber concrete at home and abroad， including the corrosion mechanism， as well as the effects of corrosion on the mechanical and durability properties of concrete. Previous studies have shown that the corrosion resistance of steel fibers is influenced by several main factors， such as the water-cement ratio， fiber type， concrete cracks， and the erosion environment. Besides， steel fibers corrode only within approximately 5 mm of the surface layer in uncracked concrete. The strength of the steel fibers gradually decreases as corrosion advances， while the corrosion products play dominant roles in the filling and compression of pores at different stages. These processes affect the bonding performance between the steel fibers and the cement matrix， thereby altering the mechanical properties of the concrete. Consequently， the mechanical properties of the concrete are closely related to the corrosion degree of steel fibers. Most existing studies have not considered the impact of the corrosion degree on the strength of steel fiber concrete， and the quantitative relationship between the corrosion degree of steel fibers and the degradation of concrete mechanical property has not been established. Finally， this paper discusses the challenges in steel fiber corrosion research and suggests future research trend.
