玄武岩纤维和玻璃纤维的耐碱性及其网格布对混凝土双向板弯曲性能的影响
|
Abstract:
为了研究玄武岩纤维网格布和玻璃纤维网格布的耐碱腐蚀性及其对混凝土方板双向受弯性能的影响，进行了玄武岩纤维和高锆玻璃纤维的耐碱试验和其网格布增强混凝土双向板的弯曲性能试验。借鉴欧洲EFNARC标准，利用四边简支方板试验，对比分析了不同纤维网格布对混凝土方板的双向增强效应。结果表明，与玄武岩纤维相比，高锆玻璃纤维的耐碱腐蚀性更好。纤维网格布较高的双向受拉性能可改善混凝土双向板的内力和应力重分布能力，玄武岩纤维网格布和高锆玻璃纤维网格布使水泥双向板的受弯承载力分别提高了48%和59%，高锆玻璃纤维的双向增强作用优于玄武岩纤维。 In order to investigate the alkali resistance of basalt fiber mesh and glass fiber mesh and their influence on the biaxial bending properties of fiber textile reinforced concrete panel, the alkali resistance test of basalt fiber and glass fiber and the biaxial flexural properties of fiber textile reinforced concrete slab were carried out. Based on the two-way slab test in accordance with EFNARC, the biaxial effect of different fiber textile was analyzed. The results show that the corrosion resistance of alkali resistance glass fiber is superior to that of basalt fiber. The high two-way tensile properties of the fiber textile can improve the inner force redistribution and stress redistribution ability of the two-way slab. The incorporation of basalt fiber mesh and alkali-resistant glass fiber mesh improves the bending resistance load capacity of the concrete matrix slab by 48% and 59%, respectively. Besides, the bidirectional reinforcement of alkali-resistant glass fiber mesh is better than basalt fiber mesh. 国家自然科学基金（51578109
