“…Benzoate compounds offer interesting possibilities for corrosion inhibition and are of particular interest because of their environmental acceptability and high solubility in water [15][16][17][18][19][20]. The inhibition effect by benzoate has been attributed to its blocking action on surface sites.…”

The influence of some organic additives on the anodic behaviour of a carbon steel electrode in contact with alkaline aqueous solutions was studied by in situ Fourier transform infrared (FT-IR) spectroscopy. FT-IR spectroscopy allows to obtain information at the molecular level regarding the metal-electrolyte interface. The following molecules have been considered: (i) benzyldimethylphenylammonium chloride (BDMPAC), (ii) glutamic acid, (iii) triethylenetetramine (TETA), (iv) sodium tartrate and (v) sodium benzoate. Potential-dependent spectra have been recorded for the different investigated systems. Quantitative information about the formation kinetics of corrosion products was derived by numerical analysis of the peak area as a function of the applied potential for the different systems investigated.

“…This pore blocking property is said to be a secondary protection mechanism against reinforcement corrosion [16,18,44,58]. Furthermore, another study reported that some organic inhibitors adsorb better on the iron surface in the active state than in the passive state [60]. Ormellese et al [61] reported that amines and alkanol amines (Table 4) had poor corrosion inhibition effect on steel in chloride containing alkaline solutions.…”

Corrosion Inhibitors, Principles and Recent Applications

The objective of the topic is to review the recent trends in corrosion inhibitors for reinforced concrete and their application in the laboratory and field conditions. Inhibitors are chemical substances which when added to the concrete in small concentrations will inhibit or prolong the time to initiation of corrosion in concrete structures. This chapter focuses on the type of inhibitors used in concrete based upon their mode of action and the way of application. The section deals with anodic, cathodic, mixed inhibitors; performance of admixed inhibitor vs. migrating/surface applied inhibitor and their evaluation studies; and electrochemical injection of corrosion inhibitor (EICI) in concrete and electrochemical chloride extraction techniques has been reviewed.

“…According to calculations, the atomic ratio Cr ox /Cr ox +Fe ox in a passive film is always larger than the chromium content in an alloy. It is observed nearly for all Fe-Cr alloys [51][52][53][54][55][56].…”
