| 摘 要： | 通过试验,提出聚丙烯纤维对混凝土的强度、脆性、弹性模量和极限拉伸值等物理力学性能的影响。结果表明:在混凝土中掺入一定量的聚丙烯纤维是克服混凝土开裂的有效途径,能有效地提高混凝土的抗裂性能。同时,探讨了聚丙烯纤维对混凝土抗裂性能影响的机理。

| Abstract: | Effects of polyprolylene fiber on phusical-mechanical properties of the concrete such as strength, brittleness, elastic modulus, ultimate elongation were presented through tests. Testing results showed that addition of a certain amount of polypropylene fiber to concrete was an effective way to prevent concrete from cracking and could effectively enhance the crack resistance of concrete. Mechanism for effects of polypropylene fiber on crack resistance of concrete was also discussed. |
