Sumario:This document reports the thermo-hydro-mechanical characterisation of the MX-80 bentonite performed at CIEMAT between 2004 and 2006 in the context of the Agreement CIEMAT/CIMNE 04/113. This Agreement took place in the framework of the Temperature Buffer Test (TBT) Project, Whose experimental part is going on at the undergroun research laboratory of Äspö (Sweden) and in which the MX-80 bentonite is used as sealing material in a large scale test. A methodology has been developed for the determination of retention curves at high temperature, what has allowed checking the decrease of the retention capacity of the bentonite with temperature. Infiltration and infiltration/heating tests have been carried out, some of them with simultaneous measurement of temperature and relative humidity.
