摘要：
In this contribution, a finite element themo-hydral (TH) modelling approach of heterogeneous cementitious material is presented. The approach is developed within the framework of partially saturated porous media. Then, a three dimensional numerical TH model has been derived and implemented in the finite element code Cast3M. Finally, some numerical examples are presented in order to illustrate the model capabilities in simulating TH behaviour of concrete by upscaling form the mesoscopic scale to the macroscopic one.
