摘要
A three-phase micromechanical model for the healed saturated concrete is presented, which is made up of the deposition products, water and intrinsic concrete. A multi-level homogenization scheme is developed to obtain the effective properties of the saturated concrete repaired by electrochemical deposition method based on the Mori-Tanaka method. Specifically, the properties of the equivalent inclusion are calculated by Mori-Tanaka method with modification function in the first level homogenization. In the second level homogenization, the Mori-Tanaka method is utilized to obtain the properties of the repaired concrete. The homogenized three-phase micromechanical model is utilized to predict the effective properties of the saturated concrete repaired by electrochemical deposition method. And the predicted results are compared with the experimental data and the existing models. Comparisons show that the proposed model can effectively predict the effective properties of saturated concrete repaired by electrochemical deposition method. When there is no repairing, they can predict the Young's modulus of saturated concrete. Based on the proposed micromechanical framework, it is found that the healed specimens have better performance when the deposition products exhibit higher properties. ©, 2014, Science Press.
