Crystallization, pore relaxation and micro-cryosuction in cohesive porous materials
Comptes Rendus. Mécanique, Volume 333 (2005) no. 6, pp. 507-512.

A poro-elastic analysis is undertaken to account for the pressure time history of water-infiltrated pores within a material subjected to freezing. The thermodynamic-mechanical equilibrium of undercooled water and ice crystal, and Poiseuille-like flow through the connection channels, combine to reveal three successive mechanisms: in-pore crystallization, in-pore partial melting and a micro-cryosuction process, driving liquid water from the yet unfrozen pores to the frozen sites. The model turns out to be apt to predict the macroscopic relaxation process observed at the onset of crystallization as reported in the literature for cement-based materials.

Une analyse poroelastisque est entreprise afin de rendre compte de l'évolution de la pression de pore dans un matériau soumis au gel. La prise en compte conjointe de l'équilibre à la fois thermodynamique et mécanique de l'eau surfondue et du cristal de glace, et d'un écoulement visqueux dans les canaux de connection, aboutit à la mise en évidence de trois mécanismes successifs : gel du pore, fonte partielle et cryosuccion, pompant l'eau des pores encore liquides vers les sites gelés. Le modèle s'avère capable de prédire le processus de relaxation macroscopique observé au début de la cristallisation tel que reporté dans la littérature pour les matériaux à base cimentaire.
