纤维素纤维及纤维混杂混凝士抗裂抗渗性能的试验研究及工程应用

摘要

In this paper, effects of the cellulose fiber, PVA fiber and hybrid fiber on concrete crack resistance and impermeability performance were studied. The test results show that, cellulose fiber and PVA fiber can improve the crack resistance and impermeability of concrete, and the effect of hybrid fiber is obvious. Engineering application shows that,for underground engineering wall of cellulose fiber concrete has .good crack resistance, impermeability and volume stability performance.%研究了纤维素纤维、PVA纤维及其两者混杂掺入对混凝土抗裂抗渗性能的影响.结果表明,纤维素纤维和PVA纤维均能有效提高混凝土的抗裂抗渗性能,两者混杂掺入对混凝土抗裂抗渗性能的改善效果明显.依托工程应用表明,用于地下工程墙板中纤维素纤维混凝土具有良好的抗裂抗渗性能和体积稳定性.
