Abstract:The objective of this paper is to present a new class of corrosion inhibitors. These organic and mixed (organic/inorganic) inhibitors are used as concrete admixtures or in repair products to delay the onset of corrosion or to reduce the rate of corrosion of steel in concrete structures. The inhibiting properties are documented in solution and in concrete. The interaction mechanism of the inhibitors with a steel surface has been studied using sophisticated surface analytical methods. The transport properties of these inhibitors are shown in mortar and concrete blocks. The inhibitors delay the onset of corrosion and reduce the rate of corrosion. They can be used as a concrete admixture, surface applied on existing structures, in repair mortars, or in grouts for rock bolts and anchors.
