摘要
从混杂纤维种类、纤维掺量及纤维尺寸等方面系统归纳了近年来混杂纤维水泥混凝土抗渗性的研究现状,总结概括了现阶段混杂纤维混凝土抗渗性的研究成果及发展趋势。混杂纤维混凝土的抗渗性研究取得重要成果,混杂纤维对混凝土抗渗性的积极效果多数学者已达成共识,未来针对纤维的几何尺寸效应、纤维与混凝土基体的界面区状态、多元混杂、化学外加剂及矿物外加剂的复合效应以及基于实际使役环境下混凝土抗渗性的变化等方面的研究仍需进一步深入。
Based on the types of hybrid fibers,fiber content and fiber size,the research status of the impermeability of hybrid fiber cement concrete in recent years is summarized.The research results and development trends of the impermeability of hybrid fiber concrete at this stage are systematically analyzed.Most scholars have reached a consensus on the positive effect of hybrid fibers on the impermeability of concrete.In the future,the effects of fiber geometric size,the state of the interface area between fiber and concrete matrix,multi-component hybrids,chemical additives and mineral additives on the impermeability of concrete need to be further studied,and the changes in the permeability of hybrid fiber concrete based on actual service environment still need to be studied in depth.
