Description
Experiments have been performed on the electrochemical
corrosion behavior of mild steel rebars
buried in concrete admired with different inhibitors
and sodium chloride salt, and exposed to dilute
sulphuric acid environment. This paper reports the
observed electrochemical corrosion response from
the electrode potential monitoring of the reinforcing
mild steel rebars during the experiments. The effect
of admired inhibitors on the compressive strengths
of the used reinforced concretes are also reported.
The added inhibitors provided varied degrees of
protection to the embedded steel rebars. Concretes
admixed with the mixture of potassium dichromate
and formaldehyde, recorded some loss of compressive
strengths; while the addition of formaldehyde
and sodium nitrite had no effect. Potassium dichromate
decreased the compressive strength of the
reinforced concretes
