掺加聚丙烯纤维改善混凝土性能的研究

针对混凝土的抗变形能力差、耐磨性差等缺点，在混凝土中掺加一定量的聚丙烯纤维，通过聚丙烯在水泥混凝土中的阻裂、增韧机理。来增加混凝土的强度、韧性及耐腐蚀性等，可以延长混凝土路面的使用寿命。

Study on Mixing Polypropylene Fiber to Improve the Performance of Concrete

To against the shortcomings of concrete such as poor anti-deformation ability, poor wear resisrance, mixing a certain amount of polypropylene fiber into concrete, which can utilize the crack arresting and toughening mechanism of polypropylene fibre in concrete to improve the strength, toughness and corrosion resistance of concrete, can prolong the service life of concrete.
