The effect of organic core–shell corrosion inhibitors on corrosion performance of the reinforcement in simulated concrete pore solution
Highlights Core-shell corrosion inhibitors presented the inhibition efficiency higher than 93%. Core-shell corrosion inhibitors halted the accumulation of corrosion products. Corrosion inhibitors adsorbed on the steel surface to form [Fen(BTA)p]m complex.
Abstract Corrosion inhibitor is widely used to mitigate corrosion damage of reinforced concrete. The objective of this study is to clarify the inhibition effect of organic core–shell corrosion inhibitors (CSCI) on the corrosion performance of the reinforcement in simulated concrete pore solution. The results indicated that the corrosion rate of the reinforcement was significantly reduced by the core–shell corrosion inhibitors. When the concentration of BTA-containing CSCI was higher than 2.27 × 10−3 wt%, the inhibition efficiency was above 93%. The inhibitors were efficiently adsorbed on the reinforcement surface and formed [Fen(BTA)p]m complex, which was beneficial for corrosion protection of the reinforcement.
