摘要
总结了混凝土界面过渡区的主要形成机制、微观特性和影响界面过渡区性能的主要因素等方面的研究成果,归纳了界面过渡区厚度、微观硬度、孔隙率和孔隙分布状态、水泥水化产物、氢氧化钙晶向指数、未水化水泥含量和微裂缝密度等参数对混凝土界面过渡区特性的影响,指出了当前混凝土界面过渡区微观特性方面需深入研究的方向。
The main formation mechanism and microstructure characteristics of the interfacial transition zone in normal temperature concrete which studied both at home and abroad are reviewed. The effects of microstructure thickness, micro hardness, porosity, distribution of pores, cement hydration products, orientation index of calcium hydroxide, unhydrated cement content and micro-crack density on the properties of interracial transition zone of concrete are concluded. Finally, the future research directions of the interfacial transition zone in concrete are pointed out.
