Modeling these processes is a challenge: in this talk, I will present a theoretical approach based on thermo-chemo-hydromechanical couplings which provides a continuous description of the hardening process. The model is confronted with a series of experiments on hydrating class G cement paste. Then, the model is implemented in a finite element code for the simulation of 3D concrete printing. A full numerical framework is developed, with automated meshing from robot data and strategies to handle sequential material deposition. Finally, applications to the prediction of collapse during printing and the study of drying related processes will be shown.<\/span><\/span><\/p>\n<p>\n<\/div><div class=\"kc-elm kc-css-74107 kc_text_block\"><\/p>\n<h2><strong>Short bio:<\/strong><\/h2>\n<p class=\"western\" align=\"justify\"><span style=\"font-size: medium;\"><span lang=\"en-US\">Maxime is a last-year PhD student at Navier (G\u00e9otechnique\/MSA\/Multi-\u00c9chelle) and will be defending at the end of the year.
