Data underlying the publication: Heterogeneous swelling of an isotropically compacted bentonite-based material: experimental observations and modelling

The swelling behaviour of an isotropically compacted sample subjected to water infiltration was investigated. The material used in this study was a mixture of Wyoming MX-80 bentonite (commercially known as WH2 Gelclay) and quartz sand with a respective proportion of 70/30 in dry mass. In order to follow the hydromechanical state of the sample during hydration, the total vertical pressure and the injected water volume were recorded over time. The cell was also equipped with four total radial pressure sensors placed at different heights of the sample. The dataset contains the injected water volume, total vertical pressure and radial pressures over time.
