聚丙烯纤维以其极好的化学稳定性和优良的技术经济性能,在土木工程复合材料中得到日益广泛的应用。阐述了聚丙烯纤维在混凝土中的作用机理和聚丙烯纤维混凝土的基本特性,并通过对添加聚丙烯纤维的混凝土进行试验对比研究,主要考查了混凝土的抗弯、抗折、抗早期裂缝等性能,得出了聚丙烯纤维混凝土在多种条件下的力学性能和物理性能特点,以及工程应用的注意事项。
Polypropylene fiber with its excellent chemical stability and excellent technical and economic performance, in civil engineering composite materials have been increasingly widely used. The mechanism of polypropylene fiber in concrete and the basic characteristics of polypropylene fiber concrete are expounded. By comparing the concrete with polypropylene fiber, the properties of concrete such as flexural resistance, flexural resistance and early crack resistance are mainly studied , Obtained the mechanical properties and physical properties of polypropylene fiber concrete under various conditions, as well as the considerations of engineering applications.
