“…Similar observation has been made by Gunasekaran et al 42 , while studying inhibition of corrosion of carbon steel by tartarate ion. Leemarose et al noticed similar observation while studying corrosion inhibition of carbon steel by sodium dodecyl sulphate 43 The various ions present in simulated concrete pore solution diffuse towards the metal surface and form a stable protective film formed on the metal surface. Equivalent circuit diagram for such a system is shown in Scheme 2.…”

Concrete admixtures can be prepared in various water samples such as rainwater, well water, and seawater. These waters contain various types of ions. So corrosion behavior of mild steel immersed in simulated concrete pore solution prepared with the above water samples will vary. Corrosion resistance of mild steel in simulated concrete pore solution prepared with above water samples has been evaluated by AC impedance spectra. The corrosion resistance of mild steel in various samples of water is as follows: Rainwater>Well water>Seawater. The corrosion resistance of mild steel in simulated concrete pore solution prepared in various water samples are in the decreasing order: Rainwater > Well water > Seawater. This is revealed by charge transfer resistance values and double layer capacitance values.

The inhibition efficiency (IE) of Amino Trimethylene phosphonic acid (ATMP) in controlling corrosion of carbon steel immersed in ground water in the absence and presence of Zn 2+ has been evaluated by weight loss method. It is observed that the synergistic formulation consisting of 250 ppm ATMP and 10 ppm of Zn 2+ has 98% IE. Polarization study reveals that ATMP-Zn 2+ system functions as a cathodic inhibitor system. AC impedance study reveals that a protective film is formed on the metal surface.

“…When corrosion rate decreases .due to formation of protective film, the charge transfer resistance value increases and double layer capacitance value decreases , the impedance value log (z/ohm ) increases. [21][22][23][24][25] . It is observed from Fcm -2 decreases and the impedance value is 3.9 log (z/ ohm ) increases.…”
