| 摘 要： | 为了计算水泥砂浆界面过渡区的弹性常数,采用广义自洽方法(GSCM),根据水泥砂浆内部的微细观结构,建立了由水泥浆基体、岩石离散夹杂(骨料)、界面过渡区(ITZ)和有效弹性材料组成的四相复合材料模型.推导了界面相的体积模量和剪切模量方程.利用已知水泥砂浆材料的实验数据,计算了界面相的弹性常数.发现界面相剪切模量约为水泥浆基体剪切模量的50%.

| Abstract: | In order to calculate the elastic properties of interfacial transition zone (ITZ) of cement mortar,this paper adopts the generalized self-consistent method (GSCM) and models the cement mortar as a four-phase composite material composed of cement paste matrix,discrete inclusions of sand (aggregate),an interfacial transition zone and effective elastic medium in terms of the internal microstructure. Equations of bulk modulus and shear modulus of ITZ are deduced and Elastic properties of ITZ are computed by usi... |
