Mesure de la perméabilité aux gaz en fonction du taux de saturation des bétons
This paper presents an experimental study about the gas permeability of different concretes versus their saturation degree. The hydric state affects indeed the transport parameters like permeability, which has a large influence on the penetration of gaseous aggressive agents and so on durability of concretes. The experimental results deal with the gas permeability measurement, saturation degree obtained by weighing or gamma-ray measurement and the pore size distribution by mercury intrusion porosimetry. The analysis points out the influence of the pre-conditioning method on the moisture gradients in the concrete samples and the influence of the concrete microstructure on the saturation degree evolution during drying. Finally, this study underlines the effect of the concrete saturation degree on the gas permeability variation.
