Results from laboratory specimens and finite element modeling are being used to better understand the apparent surface resistivity values obtained on field readings. Concrete specimens were prepared with no rebar and also specimens with two different rebar arrangements. The lab specimens were moist cured for ~ 60 days, and then transfered to lab environment for the following ~60 days, this was followed by a cyclic ponding period with 15% sodium chloride solution, the last two periods are expected to produce multilayerd concrete resistivity close to the surface.
