Mechanics Properties of Steel Fiber Reinforced Concrete

摘要

A steel fiber reinforced concrete (SFRC) pavement has not only a thickness 40%～50% less than that of a Portland concrete pavement but also have a excellent flexural strength performance and a clear priority to the common in the compatibility with foundation's local non-uniformity, which can partially cure the pavement diseases due to the foundation's non-uniform settlement and thus lift the concrete pavement adaptability. In this paper, a study is involved in some factors influencing SFRC properties, such as, randomly orientated steel fiber, fiber volume fraction Vf, fiber aspect ratio, fiber geometry, fiber spacing, fiber orientation and fiber-matrix bond strength, which aims to present some proposals for references.
