In the framework of research into radioactive waste disposal, this paper presents some tests carried out to investigate the effects of temperature between 20°C and 90°C on the changes in permeability of Boom clay. Constant head permeability tests were carried out at various temperatures and isotropic high stresses. The results show that the changes in permeability of Boom clay with temperature are only due to the changes in viscosity of free water with temperaure. This demonstrates on the one hand that the water involved in transfer at various temperatures is free water and on the other hand that there is apparently only few changes in the status of adsorbed water with respect to temperature between 20°C and 90°C.
