将柔性纤维掺入水泥混凝土可以大幅度提高混凝土的弯曲疲劳等路用性能,并通过试验建立了柔性纤维混凝土的疲劳方程。结果表明,柔性纤维不但能使混凝土的强度提高,更主要的是可以在重交通条件下,可成倍地提高混凝土的弯曲疲劳寿命。
The incorporation of flexible fibers into cement concrete can greatly improve road performance such as bending fatigue of concrete. The fatigue equation of flexible fiber reinforced concrete is established through experiments. The results show that the flexible fiber can not only improve the strength of concrete, but also can increase the bending fatigue life of concrete multiply under heavy traffic conditions.
