In recent years, with the advancement in technologies, construction engineers
have been working to replace quarry sand by raw earth in the construction
field,. For this purpose, several studies have been launched on these materials.
In this work, we have studied the corrosion of a structural steel immersed in
loamy soil. To achieve that, electrochemistry methods such as electrochemical
impedance spectroscopy (EIS), voltammetry, and free potential measurements
were performed on a radiometer, potentiometer PGZ 301 to test the samples.
The results were adjusted using ZSimpWin software to determine the kinetic
parameters such as corrosion potential and corrosion rate, The results showed
that the evolution of the corrosion rate goes through two phases, the first phase
corresponds to a decrease from an initial value around 35 µm/year to reach the
value 14 µm/year after an immersion time between 750 and 900 hours, The
second phase shows a fluctuation of the corrosion rate followed by a long
stabilization around the value 22 μm/year after 7000 hours immersion time.
The corrosion rate values obtained by the two methods, Stern Gerry and linear
polarization were compared to validate our calculations. The energy dispersive
X-ray analysis (EDS) and dynamic recrystallization (DRX) analysis showed the
formation of a passive film around the steels which was composed of different
species such as magnetite, etc., where the film plays a very important role on
the evolution of the corrosion process
