摘要/Abstract

摘要： 研究纤维编织网增强混凝土(textile reinforced concrete， TRC)外部水分沿其内部纤维束的放置走向迁移，使混凝土基体受损抗渗性能下降.分别在宏、细观层面研究了混凝土基体水灰比、纤维编织网网格尺寸、纤维束Tex含量对纤维编织网增强混凝土抗渗性能的影响，并通过核磁共振试验引入分形维数评价混凝土的粗糙程度.结果表明:纤维编织网增强混凝土的抗渗性能会随混凝土水灰比的增大、网格尺寸的减小、纤维束Tex含量的增大而降低.基于量纲分析法与试验建立了一种TRC渗流预测模型，描述了TRC的抗渗性能.

Abstract: Water in the external environment of the textile reinforced concrete(TRC)migrates along the direction of the internal directional fiber bundles， which causes the degradation of the impermeability of the internal matrix of the textile reinforced concrete. This paper studies the effects of the water-cement ratios， the textile sizes， and the fiber bundle Tex content in concrete matrix on the impermeability of TRC both in macro and micro scale. Meanwhile， the roughness of concrete was evaluated based on fractal dimension through nuclear magnetic resonance test. The results show that the impermeability of TRC decreases with the decrease of the mesh size of the textile， the increase of the Tex content and the increase of the water-cement ratio. A TRC seepage prediction model was also established based on the dimensional analysis method and permeability test， which can be used to describe the impermeability performance of TRC.

Key words: textile; concrete; impermeability; scanning electron microscope; nuclear magnetic resonance
