Influence of carbonation on chloride-induced reinforcement corrosion in simulated concrete pore solutions

Construction and Building Materials, 2014
Abstract The influence of carbonation on chloride-induced reinforcement corrosion in concrete has been studied in this work. Two different kinds of simulated concrete pore solutions, i.e. Ca(OH)2 + KOH + NaOH solution and cement extract, were applied to carry out the experiment.

Corrosion Behavior of Strained Rebar in Simulated Concrete Pore Solution

Journal of Materials Engineering and Performance, 2020
Parts of reinforcing steel bar (rebar) used in concrete are subjected to high levels of plastic strain due to various operations during construction. This work presents the corrosion behavior of pre-strained rebars in simulated concrete pore solution, both in the presence and in the absence of chlorides. Results obtained from the electrochemical tests (

Behaviour of stainless steel in simulated concrete pore solution

British Corrosion Journal, 1996
The localised corrosion behaviour of austenitic, martensitic, and duplex stainless steels has been studied in several solutions simulating the liquid present in the pores of both alkaline and carbonated concrete in the presence of chloride ions. The work aimed to evaluate the suitability of these types of stainless steel as rebars in reinforced ...

Corrosion of zinc in simulated carbonated concrete pore solutions

Electrochimica Acta, 2007
The electrochemical behaviour of pure Zn and galvanized steel in solutions simulating the pore solution of carbonated concrete has been studied by means of potentiodynamic polarization tests and polarization resistance measurements. Pure Zn was chosen because it simulates well the behaviour of galvanized steel, yielding more reproducible results.

On the corrosion behaviour of phosphoric irons in simulated concrete pore solution

Corrosion Science, 2008
Abstract 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.

Hydrogen Absorption in Iron Exposed to Simulated Concrete Pore Solutions

Corrosion, 1996
Safe 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

Evaluation of SD345 Corrosion Resistance in Simulated Concrete Pore Solution

ECS Meeting Abstracts, 2016
Reinforced 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

Corrosion of Epoxy- and Polymer/Zinc- Coated Rebar in Simulated Concrete Pore Solution

CORROSION 2009, 2009
Abstract 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, 2011
The 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

Effect of benzotriazole derivatives on the corrosion of steel in simulated concrete pore solutions

Anti-Corrosion Methods and Materials, 2007
PurposeThe aim of this research was to develop corrosion protection systems for reinforced concrete structures under chloride attack. Benzotriazole (BTA) and BTA derivatives were used as corrosion protection materials for the steel.Design/methodology/approachThe effect of BTA and four other BTA derivatives on the corrosion resistance of steel in ...
