EVALUATION OF SOIL CORROSIVITY USING ELECTRICAL RESISTIVITY METHOD: A CASE STUDY OF PART OF THE UNIVERSITY OF JOS PERMANENT SITE

Abstract: Soil resistivity could be influenced by soil moisture and concentrations of ionic soluble salts which is invariably regarded as the most comprehensive indicator of soil corrosivity. Soil corrosivity is a major concern, especially for buried infrastructure that is aging. Also, environmental protection policies now place emphasis on corrosion related issues. In view of this, the electrical resistivity of the soil of the study area were obtained to determine the corrosivity of the soil and its suitability for laying of pipes and other metals. The soil resistivity values were measured using the Wenner’s electrode configuration method. The results showed that profile 1 has resistivity ranging from 60.64 to 707.00 Ωm which indicates a practically non-corrosive to slightly corrosive potential and composed of sandy-clay to clayey sand materials. However, profile 2 has a lower resistivity ranging from 13.13 to 95.36 Ωm indicating a moderately corrosive to slightly corrosive tendencies and could be clayey in composition. Profile 4 has resistivity values ranging from 8.55 to 199.16 Ωm which reveals that the soil has a tendency to be either moderately, slightly, strongly or practically non-corrosive and this could be because of the presence of clay materials as well as nonuniformity in the composition of the soil types in this area. On the other hand, Profile 4 resistivity ranges from 15.35 to 127.31 Ωm which shows a moderately corrosive to slightly corrosive tendencies and characterized by clayey to sandy clay soils. The study area could be regarded as potentially noncorrosive, moderately corrosive and slightly corrosive.
