| Abstract | The stability of the flow induced by extrusion forming process of a cement based material is largely influenced by the relative migration between lubricating liquid phase and granular skeleton. In the present work, we propose to link rheological and soil mechanics concepts (consolidation theory, Darcy's law) to reach a simple criterion which predicts the extrusion ability of the mortar. Extrusion tests performed at different ram velocities allow validating the criterion. MOTS-CLÉS : Perméabilité, Extrusion, drainage, Mortier |
