• The effective, or relative, gas permeability of a partially saturated porous media depends on the amount of available porosity for gas percolation, its connectivity, tortuosity and pore throat diameter. It is well known that gas permeability varies significantly with the distribution and the amount of moisture present in the porous network. For each concrete, the relationship between gas permeability and water saturation has to be determined through laboratory study. In situ measurement of effective gas permeability can then be used to determine water saturation in concrete structures.
