Temperature-dependent passivation mechanisms of pre-rusted and polished steel bars in simulated concrete environments

Key Points

• Corrosion rates vary significantly between polished and pre-rusted steel bars, indicating surface condition's impact.
• At elevated temperatures, pre-rusted bars show enhanced passivation effects compared to polished variants.
• Analysis conducted in simulated concrete environments, reflecting real-world applications for construction materials.
• Findings may inform better practices to enhance corrosion resistance in steel used in concrete structures.
