| Abstract: | 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. |
