| Abstract: | Effectiveness of a new corrosion inhibitor in simulated pore solutions and mortar specimens was investigated through potentiodynamic scan,galvanostatic anodic polarization,and weight loss.The compatibility between mortar and corrosion inhibitor was also studied.The results indicated that the corrosion inhibitor delayed the onset of corrosion and reduced the rate of corrosion of reinforcing steel.Moreover,the inhibitor was found to have little effect on the performance of mortar. |
