摘　　要：讨论了混凝土界面体积百分比的计算。根据混凝土细观结构模拟技术,提出了混凝土界面体积百分比的计算方法。计算结果表明,对于给定的骨料体积百分比,界面体积百分比随着骨料最小直径的减小而增大;对于给定的骨料最小直径,界面体积百分比随着骨料体积百分比的增大而增大。基于这些模拟结果,给出了界面体积百分比的计算公式。The computation of the volume fraction of interfacial transition zone (ITZ) in concrete is discussed in this paper. Based on the computer simulation technique of concrete mesostructure, a method is presented of computing the ITZ volume fraction. The calculation results demonstrate that the ITZ volume fraction increases, for a given aggregate volume, with the decrease of the minimum aggregate diameter and increases, for a given minimum aggregate diameter, with the increase of the aggregate volume fraction. Based on the simulation results, a calculation formula of ITZ volume fraction is given.
