Localized corrosion behaviour of reinforcement steel in simulated concrete pore solution
Corrosion Science, 2009The correlation of localized corrosion behavior and microstructure of reinforcement steel in simulated concrete pore solutions was investigated. The SEM/EDS analysis showed that most of ferrite, minor amount of pearlite and some MnS inclusions existed on the steel surface.

Although much less investigated than that induced by chlorides, the corrosion of steel reinforcing bars due to bacteria metabolic products is recognised as a serious issue, primarily for concrete pipes in sewer network. In order to overcome the complications due to the preparation of concrete samples the investigation was performed using simulating ...

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 Hybrid Organic-Inorganic Coated Steel in Simulated Concrete Pore Solution
Solid State Phenomena, 2015This work compares the anticorrosion features of polysiloxane hybrid films deposited on carbon steel substrates by dip-coating. To assess the influence of the components, sol-gel coatings were prepared from condensation and polymerization of TEOS and MPTS, TEOS and MTES, TMOS and MPTS or TMOS and MTES in three molar ratios.

Molybdate-phosphate conversion coatings to protect steel in a simulated concrete pore solution
Surface and Coatings Technology, 2019Abstract For the corrosion protection of steel rebars in concrete, five different molybdate-phosphate conversion coatings were prepared, by changing the molybdate-phosphate ratio in the conversion baths. Their composition and morphology were studied with GD-OES, XPS, Raman spectroscopy and SEM-EDX and a schematic representation of their structure is ...

Effect of Sulfate on Corrosion Behavior of Reinforcing Steel in Simulated Concrete Pore Solutions
ECS Transactions, 2016Reinforcing steel in concrete is normally passivated against corrosion in the concrete pore solution with high alkalinity (often pH ≥ 12.5) resulting from the cement hydration. However, the carbonation of concrete and the presence of aggressive species may induce the breakdown of the passive film on the steel surface and the occurrence of steel ...

Abstract Corrosion of reinforcement steel forms a huge problem worldwide. A possible remedy for this problem is the application of corrosion inhibitors. The purpose of this research is to evaluate different inhibitors for both types of corrosion that can occur in reinforced concrete: pitting corrosion (by chloride attack), and uniform corrosion (by a
