Corrosion damage greatly affects the performance of steel structures, whose control
is a key aspect of design and maintenance. Hence, this paper investigates the
corrosion behavior of three different steels which are mild steel (MS), carbon steel
(CS), and stainless steel (SS) strip coupons bury in two different soil for a maximum
period of 60 days. In this study, different techniques are uses to characterize the
corrosion behavior by electrochemical impedance spectroscopy (EIS) and weight loss
(WL) measurement. The expected result is weight loss increases over time while
corrosion rates decreases. Generally, there as inverse trend between weight loss and
corrosion rates (CRS) in the coupons as the exposure period increases. It can be
concluded that weight loss tends to increase over times, corrosion rates tend to decline
simultaneously during the corrosion process.
