摘要
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。
Adding flexible fiber to cement concrete can increase the concrete pavement performance and improve the flexural fatigue property. The flexural fatigue model of flexible fiber concrete is established through tests. Test and analysis results indicate that flexible fiber can not only reinforce the stress of concrete, but also obviously promote the flexural fatigue life by the great stress.
