废旧橡胶粉与聚丙烯纤维混杂混凝土性能研究

本文通过对橡胶粉与聚丙烯纤维混杂混凝土的28天龄期的抗压强度、劈裂抗拉强度、强度恢复性能、容重等力学性能研究分析，探讨混杂对混凝土性能的改善效果，并得出了初步结论。其拌合物的工作性能要优于单一的聚丙烯纤维混凝土；相同掺量的混杂混凝土比单一胶粉混凝土的抗压强度有所提高；混杂混凝土劈裂抗拉强度明显增强，并具有极好的强度恢复性能。

Study of Waste Arubber Powder and Polypropylene Fiber

Through to rubber powder mingled with polypropylene fiber concrete 28 days compressive strength,splitting tensile strength,strength restore performance,bulk density of mechanical properties are analyzed,hybrid of concrete performance improvements,and draw a conclusion.The thing work is regarded mix-proportion performance than single polypropylene fiber concrete.The same dosage of confounders concrete than single powder concrete compressive strength improved.Mixed concrete splitting tensile strength is enhan...
