摘要
在室内小梁疲劳试验的基础上,分析疲劳寿命试验数据的概率分布,证实掺加改性剂后的多孔混凝土疲劳寿命服从双参数的威布尔分布。通过对比分析,得出这种新型改性剂对改善多孔混凝土疲劳性能有很好的作用,并分析了该改性剂产生作用的原因和机理。
On the basis of the flexural fatigue test of a small porous concrete beam in the laboratory, the probability distribution of fatigue life data is analyzed in the paper, the results of which prove that the fatigue life of porous concrete with a new modifier added is in agreement with the two- parameter WEIBULL distribution. Through analyses and comparison, it is found that the modifier has positive effects on the fatigue performance of porous concrete. And the causes and mechanism of the effects of the modifier are also analyzed.
