混凝土微观结构特性对耐久性的影响

摘要

针对混凝土使用过程中出现的由于耐久性不足所产生的问题,借助于电子显微镜技术对混凝土材料从微观层次上进行研究,通过对混凝土材料微观结构的观察得出混凝土界面过渡区是混凝土结构中最薄弱的结构区,改善混凝土界面过渡区可以显著提高混凝土的性能.%The problem caused by the lack of concrete durability often occurs. The performance of concrete mate-rials is researched at the micro level with the use of the electron microscope technology. Through the observation of the microstructure of concrete material, it turns out that interfacial transition zone of concrete is the weakest zone concrete in structure and improving the interfacial transition zone of concrete can significantly improve the performance of concrete.
