The Effect of Both Moisture and Clay Content on The Soil Corrosion Process for Different Periods of Time as A Geomorphological Study in Al-Kut City

Abstract

Soil corrosion is a major hazard to subterranean infrastructure including gas and oil transmission pipes, underground storage tanks and others. The impacts of soil engineering characteristics on buried mild steel coupons’ metal loss are investigated in this work. Soil characteristics such as soil clay and moisture content are the focus of the present research in Al-Kut city near Tigris River. For a twelve month period, 100 pieces of mild steel coupons were put underground in five different sites across to look into the effects of the aforementioned variables on loss of metal owing to corrosion of soil. Every three months, the samples were recovered to evaluate the rate of weight loss and corrosion rate development. The data show that the high moisture content of the soil is linked to rapid corrosion development. Corrosion on clay soil, on the other hand, takes longer to start. According to the qualitative assessment, soil moisture content has a greater impact on corrosion dynamics than clay content.
