The resistivity evolution vs. time of concrete prepared with three different compositions and subjected to various curing regimes for an extended period of time was studied. Two of the curing regimes consisted of immersing the specimens in either tap water or 3.5% NaCl solution. The other three curing regimes consisted of exposure to: fog room, high humidity and laboratory humidity. The measured resistivity values were then used to estimate the aging factor. It is found that the aging factor is time dependant for concrete with mineral admixtures. The curing exposure affects the magnitude of the aging factor.
