Study of Corossion Potential in Subsoil Resistivity

Abstract

The degradation of a substance or its qualities as a result of a reaction with the environment is known as corrosion. Corrosion is a natural process that can take place in almost any substance, but it is most commonly linked with metal. The resistivity of the soil is the one variable that has the most significant impact on the pace of corrosion. Metal that is buried in soils with a low resistivity will, in most cases, become anodic, whereas metal that is buried in soils with a high resistivity will, in most cases, become cathodic. In order to prevent and protect the corrosion of buried metallic structures by underground soil, a soil resistivity field study carried out at Merauke District. The results of the research and interpretation of soil resistivity data that have been carried out can be said that the subsoil structure of the three measurements was identified as topsoil, silty soils, sandy soils, and clayey soils. Sandy and clayey soils that have low soil resistivity values between 2.22 – 11.3 Ωm have the potential to be highly corroded. Topsoil which has a high soil resistivity of 590.0 Ωm can pose a danger if the existing mud causes the water content of topsoil to increase.
