Abstract
In the case of buildings consisting of reinforced concrete, vulnerable problems (such as steel-reinforcement corrosion and concrete cracks) may occur due to concrete carbonation depending on external environmental conditions such as temperature, moisture and CO2 concentration. Since concrete carbonation is significantly important degradation factor that could determine the lifetime of the building, functional coatings (paints) are attracting attention as a means of preventing it. This review provides the current status of highly functionalized paints for preventing concrete carbonation in South Korea and the direction for improving paints.
