聚丙烯纤维对再生混凝土拉伸力学性能的影响

Effects of Polypropylene Fiber on Tensile Mechanical Properties of Recycled Concrete

通过聚丙烯纤维再生混凝土单轴拉伸力学性能试验,分析研究了聚丙烯纤维对再生混凝土拉伸力学性能的影响。结果表明,掺一定量的聚丙烯纤维对再生混凝土的抗拉性、抗裂性有很大的提高,可解决再生混凝土拉伸力学性能低等影响工程应用的问题。

Through the uniaxial tensile mechanical properties test of recycled polypropylene fiber concrete, the effects of polypropylene fiber on the tensile mechanical properties of recycled concrete are analyzed and studied. The results show that adding a certain amount of polypropylene fiber can greatly improve the tensile and fissure resistance of recycled concrete, which can solve the problems such as lower tensile mechanical properties of recycled concrete.
