An analytical method is presented for predicting the elastic modulus of concrete with the inhomogeneous interfacial transition zone (ITZ).

提出了考虑不均匀界面时混凝土弹性模量预测的解析法。

youdao

The interfacial transition zone (ITZ) of concrete cured in standard condition and in the dry and wide temperature change environment was studied comparatively.

采用显微硬度仪和扫描电镜，对比研究了干燥大温差气候条件和标准养护条件下混凝土界面过渡区的结构和形态。
