CORRELATION BETWEEN SOIL ELECTRICAL RESISITIVITY AND METAL CORROSION BASED ON SOIL TYPES FOR STRUCTURAL DESIGNS

Abstract: Soil resistivity measurements are an important parameter employed in the designing earthing installations. Thus, the knowledge of soil resistivity with respect to how it varies with related parameters such as moisture content, temperature and depth, at the intended site, is very vital in order to determine how the desired earth resistance value can be attained and sustained over the life of the installation with the lowest cost and effort. The relationship between corrosion and soil resistivity has been investigated in this work. Various soil samples; Sand, Gravel, Loam, Clay, and Silt, were collected from different spot within the vicinity of Ogbomosho land, Nigeria. The resistivity of the soil sample was determined through the Wenner method. The result shows that clay sample has resistivity ranging between 500 and 2000 Ω cm which indicates high corrosion potential while sand sample with resistivity in the range of 10,000 to 500,000 Ω cm indicates low corrosion potential. Corrosion of the soil samples was found to be enhanced by low resistivity and low hydraulic conductivity in soils.
