聚丙烯纤维混凝土力学耐久性能研究

Study on Mechanical and Durable Performances of Polypropylene Fiber Reinforced Concrete

通过试验研究聚丙烯纤维对混凝土的力学性能和耐久性能的影响,主要探讨聚丙烯纤维对混凝土立方体抗压强度、抗折强度、劈拉强度、脆性性能、抗渗性、抗冻性的影响规律,并进行机理分析,为纤维混凝土的理论研究积累试验数据,为聚丙烯纤维混凝土在工程中进一步推广和使用提供依据。

By studying the influence of polypropylene fiber on the mechanical properties and durability of concrete,the effect of polypropylene fiber on the compressive strength,flexural strength,splitting strength,brittleness,impermeability,frost resistance of concrete cube is discussed in this paper.In addition,the action mechanism of polypropylene fiber on concrete is analyzed to accumulate test data for the theoretical study of fiber reinforced concrete and provide references for the popularization and application of polypropylene fiber reinforced concrete.
