Effects of Vitamins as Green Inhibitors on the Surface of Steel Bars in Chloride-Polluted Simulated Concrete Pore Solution: Experimental, Characteristic Analysis, and Theoretical Calculation.

This study evaluates the effects of vitamins B1 (VB1), B6 (VB6), B3 (VB3), and C (VC) as green corrosion inhibitors for steel bars in a chloride-polluted simulated concrete pore (SCP) solution. Electrochemical tests demonstrated that VB6 achieves the highest corrosion inhibition efficiency (IE%) of 92.86%, and the IE% of VB1 and VC are 91.
