Concrete is the second most used construction material in world after water. Concrete may be considered as best construction material but its durability can adversely be affected by various means. Corrosion of steel present in reinforced concrete is most significant durability problem in the world of Civil Engineering. Many Highway Projects have been stalled due to various issues leading to termination of Contracts. This results in partially completed structures which leads to corrosion of reinforcement exposed to atmosphere. Corrosion can cause reduction in strength, expansion or mass loss in concrete. Hence, many methods have been developed to reduce or prevent corrosion of steel in concrete. From all the methods available for corrosion protection, corrosion inhibitors sound very promising. Inhibitors that are available in market usually have a tendency to protect against only one factor of corrosion i.e. either carbonation or chlorides along with the fact that commercially available corrosion inhibitors are very expensive and affect the total cost of structure. Due to which, there arises a need to find a cheaper replacement which can inhibit corrosion due to carbonation and presence chlorides. In this study, assessment of corrosion of reinforcement in partially completed structures and retrofitting using corrosion inhibitors such as Picolinic Acid, 4-Aminobenzoic acid, 2-Salicylaldehyde and 2-Aminopyridine with 1% addition has been carried out.
