The effect of a new generation surface-applied organic inhibitor on concrete properties

The influence of a new organic surface-applied corrosion inhibitor (SACI) on selected concrete properties is studied including compressive strength, tensile strength, steel-concrete bond strength, permeability, drying shrinkage, and freeze-thaw resistance. The inhibitor is an aminoalcohol-based (AMA) corrosion inhibitor and it is applied on the hardened concrete surface. The results show that the inhibitor can be used safely and it does not have any significant harmful effect on the properties of hardened concrete and it improves some properties of concrete with its pore-blocking effect.
