摘　　要：对掺入聚丙烯纤维的RPC进行了力学性能分析,发现其抗压强度具有较大幅度的提高,冲击韧性也显著增强;对其疲劳寿命进行线性回归分析发现,疲劳寿命可以很好地服从两参数Weibull分布;聚丙烯纤维可极大提高RPC的疲劳寿命。The mechanical properties of reactive powder concrete （RPC） with polypropylene fibers are analyzed and it shows that the compressive strength has improved greatly and its impact toughness is significantly enhanced. Linear regression analysis on its fatigue life shows that the fatigue life obeys the distribution of two-parameter Weibull well and the pnlypropylene fiber can improve the fatigue life of RPC greatly.
