Concrete is the second most common building material in the world, behind water. Concrete may be regarded as the greatest building material, yet it is susceptible to deterioration due to a variety of causes. A major problem in Civil Engineering is the corrosion of steel in reinforced concrete. 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. Concrete's strength, expansion, and mass can all be affected by corrosion. As a result of the several tactics developed to reduce or eliminate steel corrosion in concrete, corrosion inhibitors appear to be the most promising of all corrosion preventative measures. Commercially available corrosion inhibitors are quite expensive and have an impact on the overall cost of the construction because they only guard against one kind of corrosion, either carbonation or chlorides. This necessitates the need for a less expensive substitute that can prevent corrosion caused by carbonation and the presence of chlorides. In this investigation, corrosion inhibitors such as Picolinic Acid, 4-Aminobenzoic acid, Salicylaldehyde, and 2-Aminopyridine with a 1% addition were examined and fitted.
