![]() The duration of exposure of steel to corrosive soil environment is also a factor in the rate of corrosion noticed in the exposed steel. Average and instantaneous corrosion rates in Q235 steel coupons buried in soils with different moisture content showed corrosion rate more in soil with 26% moisture than in soil with 12% moisture. A general trend is that corrosion rates in soil increases with increased moisture content. One critical factor in soil corrosion is the moisture content of the soil. Reference defined soil-corrosion as the deterioration of metal or other materials brought about by chemical, mechanical and biological action by soil environment. The corrosiveness of soil can be defined as the capacity of producing and developing the corrosion phenomenon. When metals are exposed to the soil, they begin to corrode. ![]() It was observed that APWL increased by nearly the same ratio that CR decreased during the period of exposure of the coupons. This trend was observed in all three coupons and at both sites, except for a few excursions which did not significantly affect the established trend. It was observed that generally, there was an inverse trend between weight loss and corrosion rates in the coupons as the exposure period increased such that, while APWL values were seen to be increasing, CR values were decreasing. For the SS coupon, APWL and CR were 0.12% and 0.32 mpy, respectively from the water-logged soil and, 0.08% and 0.19 mpy, respectively for the sandy soil site. Similarly, APWL for the CS coupons from the water-logged soil and sandy soil sites were 4.5% and 3.6%, respectively while their CRs were 3.51 mpy and 3.67 mpy, respectively. The corresponding CRs were 5.58 mpy and 3.18 mpy, respectively. Post-exposure analyses of the coupons over the entire period showed that the APWL for the MS coupons retrieved from the water-logged soil and sandy soil sites were 5.4% and 2.8%, respectively.
