The existing single concrete composite material mainly consists of sand, cement and water reducer, thus having poor anti‐freeze and anti‐collision capacities. In this study, polypropylene fiber reinforced concrete composite is prepared by adding polypropylene fiber into composite material. Therefore, the polypropylene fiber added to the concrete method of composite materials There are two methods of adding polypropylene fiber, i.e. adding polypropylene fiber first and polypropylene fiber later, and the fiber distributions of as‐prepared polypropylene fiber concrete composites under two method were compared. In this work, the method of adding polypropylene fiber first was selected.The amount of allocation of strength in the process of operationBy selecting the cement, aggregate and polypropylene fiber materials needed for the preparation of polypropylene fiber composites, and calculating the strength, water‐binder ratio, the amounts of polypropylene fiber and water‐reducing agents in the process of configuration, polypropylene fiber concrete composites is successfully prepared in this work.The experimental results show that the concrete composite made of polypropylene fiber has a high improvement in the antifreezing and anti‐collision ability.

聚丙烯纤维增强混凝土复合材料的制备及性能分析

现有的单一混凝土复合材料主要由沙子,水泥和减水剂组成,因此防冻和防撞能力差。在这项研究中,聚丙烯纤维增强混凝土复合材料是通过将聚丙烯纤维添加到复合材料中来制备的。因此,将聚丙烯纤维添加到复合材料的混凝土方法中有两种添加聚丙烯纤维的方法,即先添加聚丙烯纤维,然后添加聚丙烯纤维,并比较了两种方法制备的聚丙烯纤维混凝土复合材料的纤维分布。在这项工作中,选择了首先添加聚丙烯纤维的方法。在操作过程中强度的分配量通过选择水泥,
