The Effect of Temperatures on the Passivation Behavior of Q235 Steel in the Simulated Concrete Pore Solution. [PDF]
Materials (Basel), 2023 Concrete, especially mass concrete, releases a large amount of heat during the hydration process, resulting in the passivation of reinforcement at high temperatures. However, the passivation study of reinforced concrete is mostly conducted at room temperature, and the influence of temperature on passive film behavior is not clear at present.

Effect of NaCl Solution and Simulated Concrete Pore Solution Environment on the Efficiency of Steel Bar Energized Corrosion. [PDF]
Materials (Basel), 2022 As the main problem of the durability deterioration of concrete structures, the corrosion of steel bars is usually made by the method of electrified corrosion with a short cycle and low cost. However, there is a big difference between the actual corrosion depth and the theoretical corrosion depth after the reinforcement is electrified.

Improved Corrosion Resistance of Magnesium Alloy in Simulated Concrete Pore Solution by Hydrothermal Treatment. [PDF]
Scanning, 2020 Magnesium alloys are considered for building materials in this study due to their natural immunity to corrosion in alkaline concrete pore solution. But, chloride ions attack often hinders the application of most metals. Therefore, it is necessary to conduct a preliminary corrosion evaluation and attempt to find an effective way to resist the attack of ...

Copper Corrosion Behavior in Simulated Concrete-Pore Solutions [PDF]
Metals, 2020 The copper corrosion was studied for 30 days in two alkaline electrolytes: saturated Ca(OH)2 and cement extract, employed to simulate concrete-pore environments. Electrochemical Impedance Spectroscopy (EIS) and Cyclic Voltammetry were carried out at the open circuit potential (OCP), and potentiodynamic polarization (PDP) curves were performed for ...

Effectiveness of corrosion inhibitors in simulated concrete pore solution [PDF]
European Journal of Environmental and Civil Engineering, 2018 10 Steel embedded in concrete is normally in a passive state against corrosion due to a thin iron 11 oxide layer that forms on the steel surface and remains stable in the high alkaline environment 12 of the concrete. This protective film must be destroyed (depassivation) and this can be mainly 13 done in two ways: by the attack of chlorides on the ...

Corrosion Resistance of Mild Steel in Simulated Concrete Pore Solution [PDF]
Chemical Science Transactions, 2013 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.
