Corrosivity based on soil resistivity
Soil resistivity is one of the driving factors determining the corrosiveness of soil. The soil corrosiveness is classified based on soil electrical resistivity by the British Standard BS-1377 as follow: ρE > 100 Ωm: slightly corrosive50 < ρE < 100 Ωm: moderately corrosive10 < ρE < 50 Ωm: corrosiveρE < 10 Ωm: severe See more Soil resistivity is a measure of how much the soil resists or conducts electric current. It is a critical factor in design of systems that rely on passing current through the Earth's surface. It is a very important parameter for … See more Because soil quality may vary greatly with depth and over a wide lateral area, estimation of soil resistivity based on soil classification … See more • Wenner, Frank (1916).
