活性粉末混凝土(简称R.PC)是一种新型水泥复合基材料,由于具有超高强度、高韧性、高耐久性等优良性能而受到越来越多的学者的关注与研究,随着我们研究的逐步加深,RPC材料也会越来越多的被应用于实际工程中.通过三种不同钢纤维体积掺量的试件进行抗折疲劳试验,研究了RPC的疲劳寿命分布,疲劳试验获得了试件的抗折疲劳加载次数,并用疲劳统计学理论验证了RPC疲劳寿命的威布尔分布.
Reactive powder concrete (referred to as R.PC) is a new type of cement-based composite material, which has attracted more and more scholars’ attention and research due to its excellent properties such as high strength, high toughness and high durability. As we studied RPC material will also be more and more applied in practical engineering.Through three kinds of different steel fiber volume content of the specimen for the flexural fatigue test, the study of the RPC fatigue life distribution, the fatigue test was obtained The flexural fatigue loading times of the specimens and the Weibull distribution of RPC fatigue life were verified by fatigue statistics theory.
