On the corrosion behaviour of phosphoric irons in simulated concrete pore solution
Corrosion Science, 2008Abstract The corrosion behaviour of three phosphoric irons P1 (Fe–0.11P–0.028C), P2 (Fe–0.32P–0.026C) and P3 (Fe–0.49P–0.022C) has been studied in simulated concrete pore solution (saturated Ca(OH)2 solution) containing different chloride concentration.

Evaluation of SD345 Corrosion Resistance in Simulated Concrete Pore Solution
ECS Meeting Abstracts, 2016Reinforced concrete known as high strength material has been used for social infrastructure for a long time. However, the number of infrastructures used for more than 50 years has been increasing year by year, and deterioration of their durability is concerned. It is well known that corrosion of reinforcing steel leads to concrete cracks. It means that

Hydrogen Absorption in Iron Exposed to Simulated Concrete Pore Solutions
Corrosion, 1996Safe cathodic protection (CP) limits are required for prestressed steel in concrete to avoid the risk of hydrogen embrittlement (HE). A CP protection potential more positive than the reversible hydrogen potential is one approach for avoidance of HE. However, it has been demonstrated in the literature that the steel tendon can drop locally well negative

Corrosion of Epoxy- and Polymer/Zinc- Coated Rebar in Simulated Concrete Pore Solution
CORROSION 2009, 2009Abstract This work is a preliminary examination of mechanistic issues on the comparative corrosion performance of regular epoxy-coated rebar (ECR) and dual polymer-zinc coated reinforcement (DCR) in simulated concrete pore solution with and without chloride ions, at polarizations from +100 mV to -1000 mV in the saturated calomel ...

Electrochemical corrosion behavior of HRB500 steel bar in Simulated Concrete Pore solutions
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011The electrochemical corrosion behavior of HRB500 steel bar in Simulated Concrete Pore (SCP) solutions contaminated by bicarbonate ions and (or) chloride ions was investigated by cyclic potentiodynamic polarization technique, and it was compared with that of HPB235 steel bar. The results show that the passivation and repassivation of HRB500 steel bar is

Steel Corrosion-Inhibiting Effect of Sodium Nitrate in Simulated Concrete Pore Solutions
Corrosion, 2011Abstract When chloride-induced corrosion takes place, a local acidification occurs at the corrosion pit. Therefore, it is necessary to study the performance of corrosion inhibitors in low-pH environments. Reinforcing steel bars have been exposed to solutions that simulate the electrolytic environment of concrete micropores during the ...

A study on chloride-induced depassivation of mild steel in simulated concrete pore solution
Cement and Concrete Research, 2002The effect of chloride ions on passivity breakdown of steel in simulated concrete pore (SCP) solution was studied using electrochemical techniques. In this regards, the sensitivity of cyclic potentiodynamic parameters such as ΔE (difference between Epit and Erep), ipeak and AC-impedance parameters like Rct, Rf, Ci, Rad and Cad to chloride ion ...

The corrosion of reinforcement has always been a problem to be solved in the field of architecture. In this paper, the corrosion characteristics of chromium alloy steel under different pH conditions are studied. The impedance characteristics and equivalent circuit are predicted by neural network model.
