the SEALEX experiment, performed in the Tournemire Underground Research Laboratory, run by IRSN in France, aims at identifying conditions that will affect the performance of swelling clay-based sealing systems. Current experiments focus on a 70/30 MX80 bentonite-sand mixture compacted at dry densities between 1,67Mg/m2 and 1,97 Mg/m2. Prior to the in-situ tests, a 1/10th scale mock-up has been tested and proposed as modelling benchmark, in the framework of the international project DECOVALEX. Three independent research teams have worked towards modelling the three phases of this experiment, using different codes and input parameters. In the paper, blind predictions and model calibrations of the three phases are compared to the experimental measurements and discussed.
