摘要Laboratory investigation was carried out to assess the effect of amino-alcohol-based corrosion inhibitors on concrete durability, and the inhibition mechanism in concrete was analyzed. Both admixed type and surface-applied type corrosion inhibitors were studied by chloride penetration test, saturation test, scanning electron microscope, and X-ray diffraction. The results showed that the anti-penetrability, compactness, and hydration of concrete were improved after the two types of corrosion inhibitors were applied. The use of corrosion inhibitors mitigated the penetration of chloride ions and water into concrete, which effectively delayed corrosion of the reinforcing bar. The surface-applied corrosion inhibitor showed better efficiency in the concrete specimens compared to the admixed type. Moreover, there was a better synergy between the two agents and the best performance when the two agents were applied to the concrete simultaneously.
