Anisotropic features on the thermal conductivity of a deep argillaceous formation

Research output › peer-review

Abstract

An experimental study on Ypresian clays –one of the potential deep and sedimentary clay formations in Belgium for the geological disposal of heat-emitting radioactive waste– has been undertaken to systematically study anisotropic features on the thermal conductivity using a setup with thermal flux measurement. A careful pre-conditioning protocol before the thermal tests has been followed to ensure a very high degree of saturation and the closure of fissures / gaps along bedding planes. Thermal conductivity data with this improved preconditioning protocol allowed obtaining results consistent with the values reported when using back-analysis in a constant volume cell with fully saturated material.
