N2 - Experience has shown that repairs of concrete structures are often subject to premature cracking because the already dry and rigid substrate of the damaged structure contrasts the drying and self-drying contractions of the new material of restoration. In this paper a thermo-hygro-chemo-mechanical (THCM) model for concrete at early age is presented and used to analyze the behaviour of a real repair case taking into account casting and environmental conditions. The multi-physics mathematical model is a simplified version of COMES-HTC (developed a few years ago by Gawin, Pesavento & Schrefler, 2006). The THCM model for concrete at early age has been implemented in the French finite elements code CAST3M (developed by the CEA, Commissariat à l'Energie Atomique Français).
