During the PhD, a compacted bentonite-sand mixture was investigated as a candidate material for the expansive core. Its hydromechanical-gas behaviour was characterized by capturing the phenomenon of water imbibition at unsaturated conditions and the gas migration at saturated conditions. Test were performed using advanced imaging techniques (MRI and X-Ray \u00b5CT). The results validated the effectiveness of candidate material as hydraulic plug, slowing down water infiltration, while allowing gas migration at relatively low pressure.<\/span><\/span><\/p>\n<p>\n<\/div><div class=\"kc-elm kc-css-384782 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\">Pablo Eizaguirre is a PhD student at the Navier Laboratory in collaboration with Andra (National Agency for Radioactive Waste Management).
