界面过渡区被认为是混凝土的薄弱环节，对混凝土的性能有较大的影响。针对界面过渡区结构和性能特点，综合国内外的研究成果，根据混凝土的成型和水化硬化过程，探讨了界面过渡区的形成机制。从混凝土的强度、弹性模量以及断裂力学性能等3个方面，综述了界面过渡区对混凝土力学性能的影响，并论述了其对混凝土传输性能的影响。通过加入辅助性胶凝材料改善界面过渡区的孔结构和分布，同时选取适宜的骨料、W/C等可以改善ITZ与基体之间的性能差异，减少ITZ对混凝土力学性能的不利影响。

The interfacial transition zone between cement Paste and aggregate which is considered to be the weakest zone in concrete has a significant influence on the mechanical ProPerty of concrete. According to the structure and Performance characteristics of the interfacial transition zone and based on research at home and abroad as well as the hydration and hardening Process of cement - based materials,this article briefly discusses the formation mechanism and reviews its influence on the mechanical ProPerties from the asPect of strength,elastic modulus and fracture mechanics ProPerties, and the transPortation Performance. Adding aPProPriate level of suPPlementary cementing materials, which could imProve Pore structure and distribution,and choosing aPProPriate aggregate tyPe and water cement ratio,could lower the Performance difference between the ITZ and the substrate ,thus reducing the adverse effect of ITZ on the mechanical and transPortation ProPerties of concrete.
