摘要
试验研究了合成纤维混凝土的抗冻融、耐高温及耐磨性,结果表明:相对素混凝土,合成纤维混凝土的抗冻融性显著提高;膨胀爆裂概率降低了57%;磨耗量降低35%～19%。表明合成纤维混凝土的耐久性能优越,对提高混凝土水利工程的耐久性具有重要意义。
This paper presents an experimental investigation on freeze-thaw resistance, high-temperature and abrasion-erosion resistance of synthetic fiber reinforced concrete. Compared to plain concrete, the freeze-thaw resistance of synthetic fiber reinforced concrete was increased remarkably, probability of expand and blowout was decreased 57 %, quantity of abrasion-erosion was reduced 35 %- 19%, which indicates that en durance of synthetic fiber reinforced concrete is excellent, it has significance to improve the endurance of hydroprojects.
