摘要
在混凝土中掺加聚丙烯纤维能有效地提高混凝土材料的抗裂性、抗冲击性、抗冻性能、改善混凝土的抗疲劳特性。分析了纤维改性混凝土机理。介绍了聚丙烯纤维在混凝土中的应用。指出了聚丙烯改性混凝土的发展趋势以及加强高性能、多功能以及复合聚丙烯纤维改性水泥土研究的重要性。
The properties of crack resistance,impact resistance, frost resistance and fatigue resistance of cement were improved by adding polypropylene fiber. Mechanism of fiber modifying cement were analyzed. The application of polypropylene fiber in cement was introduced and the development of polypropylene fiber cement was pointed out. Research on high capable, more functional and complex polypropylene fiber modifying cement was important.
