Indeed, chloride transport across the porosity of concrete coating produces medium to long-term corrosion of reinforcements. This has a direct impact on the mechanical behavior and the ageing of the affected structures. The difficulty of in situ monitoring of these structures, continuously and non-destructively against infiltration of chlorides, is still topical. The work presented here aims mainly at correlating the electrical properties, i.e. electrical resistance, conductivity..., with the physical characteristics (porosity, tortuosity, ...), of granular materials using Archie's law. The recommended experimental program consists in placing, different granular materials, i.e. sand, mortar, bricks, and concretes saturated with electrolytic solutions, in a PVC cell fitted with a pair of stainless steel electrodes connected to an electrical circuit, in order to measure the electrical resistances. The results obtained allow one to determine durability factors, such as the connected porosity and the coefficient of chloride diffusion through a simple measurement of the EC, and estimate the tortuosity parameter that governs transport in porous media.
