摘要 在室内进行了粉煤灰再生混凝土小梁的弯曲疲劳试验,采用威布尔模型,得到了粉煤灰再生混凝土的疲劳方程,并与普通水泥混凝土以及粉煤灰贫混凝土的疲劳方程做了比较.结果表明,粉煤灰再生混凝土的疲劳性能与普通水泥混凝土相似,特别是在应力水平较低部分基本一致,粉煤灰再生混凝土能够承受行车荷载的重复作用. Flexural fatigue tests on beams of recycling concrete with fly ash were performed in the laboratory. A fatigue equation for the probability of failure of the recycling concrete with fly ash was derived according to the Weibull probability distribution. The fatigue equation was compared with one for Portland cement concrete and one for lean concrete with fly ash. The results show that the flexural fatigue performance of the recycling concrete with flay ash is similar to that of Portland cement concrete,especially at low stress. Recycling concrete with fly ash can satisfy the needs of repeated vehicle loads.
