Use of Modified Hydrotalcites (MHTs) as a New Type of Smart Additive of Reinforced Concrete for Improved Corrosion Protection: An Electrochemical Performance Assessment in Simulated Concrete Pore Solution

MHTs (MHT-p, MHT-N) represented superior corrosion inhibition effect against chloride induced pitting corrosion in simulated concrete pore solution when compared with the pure inhibitors (pAB, NaNO2). Among them, MHT-p exhibited a better improvement of inhibition effect than MHT-N. This result is probably caused by the bigger ion exchange capacity between pAB ion and chloride ion in MHT-p. MHT-p was almost as effective as NaNO2.
