Abstract

Corrosion of reinforced concrete structures is a major problem throughout the world, demanding significant amounts for repair and rehabilitation, mainly when the rebar in the concrete is exposed to the chlorides either contributed from the concrete ingredients or penetrated from the surrounding chloride-bearing environment. Carbonation of concrete or penetration of acidic gases into the concrete, are the other causes of reinforcement corrosion. Chemical corrosion inhibitors present an alternate method for preventing and/or delaying corrosion of reinforcement in concrete. However, it is essential that the mechanism of inhibition be understood to ensure proper use. This review of the various possible mechanisms of inhibition is presented. Two types of corrosion inhibitors (nitrite and organic inhibitors) are compared.
