Soil resistivity corrosion chart

WebDec 11, 2024 · Soil resistivity is a measure of how much soil can resist electrical flow, determined by its moisture content. As moisture increases, soil resistivity decreases. This … WebThe properties of soil that have the most effect on the corrosion rate of zinc are aeration, moisture content (or time of wetness), pH, temperature, and resistivity. Generally speaking, sandy, well-aerated soils with a neutral or slightly basic pH are likely to cause only limited corrosion of zinc , most likely below ten microns per year (0.4 mil/year).
