✦ Synopsis

The overall elastic moduli of concrete composite materials are investigated in this study by employing the theory of micromechanics. A method based on Mori-Tanaka Theory and double inclusion can provide a more accurate evaluation of the average elastic relationships of concrete composite materials. The inclusions are divided into two groups: fine aggregate and coarse aggregate. Moreover, the overall elastic moduli of the concrete composite materials are given as a function of properties and volume fraction of the following three components: fine aggregate, coarse aggregate, and cement paste. A comparison is also made between the theoretical results and published experimental data.
