Abstract

Some electrochemical techniques such as linear polarization,electrochemical noise and EIShave been employedto study the inhibition behavior of N-lauroyl sarcosinate,β-sodium glycerophosphate and D-sodium gluconate for the reinforcing steel immersed in simulated concrete pore solution(SPS) with NaCl addition.The results show that D-sodium gluconatehas an obvious inhibitive effect for the reinforcing steelin containingCl~(-)SPS solution.It has been proposed that the corrosion inhibition of D-sodium gluconate is due to its competitive adsorption and precipitation on steel surface in the simulated concrete environment.
