通过反向散射 SEM 图像的图像分析研究混凝土界面过渡区 (ITZ) 时需要考虑的一些因素。其中包括混凝土的选择和取样、选择用于 ITZ 测量的单个骨料以及围绕所选骨料设计和定位单个取样单元。重点强调分析骨料周围性质的横向变化以及平均成分随距骨料距离的变化的重要性。说明了可应用于结果解释的统计考虑因素。
A number of considerations are discussed with regard to the study of the Interfacial transition zone (ITZ) in concrete by image analysis of backscatter SEM images. These include selection and sampling of the concrete, selection of individual aggregates for the ITZ measurements, and design and positioning of individual sampling units around the chosen aggregates. Emphasis is placed on the importance of analyzing the lateral variation in properties around the aggregate as well as variation in mean composition with distance from the aggregate. Statistical considerations that can be applied to the interpretations of the results are illustrated.
