résumé The evaluation of the in situ moisture state of concrete is of great importance to understand the behavior of a structure and ensure its durability and integrity. A measurement device based on relative gas permeability measurement to determine concrete moisture has been designed. The results of a laboratory validation study are presented in this article and show the efficiency of this moisture measurement method. The device has been installed on a nuclear waste disposal site in France and the feasibility of an in situ experiment is also discussed.
