Abstract—By the carbonation process concrete construction absorbs carbon dioxide from surrounding environment. This absorbed carbon dioxide reacts with the calcium oxide, which is already present in Reinforced concrete (RC) and form calcium carbonate an acidic compound that enhances corrosion on the surface of the reinforcement. Addition of photo catalytic materials to the RC structure during its construction phase could reduce the corrosion problem of RC materials. This material hinders calcium oxide to form acidic compound and creates a complex compound. In combination with light, this complex compound is oxidized, and residual compound will exist in or surface of RC material. In this study we find out a new photo catalytic material LiNbO3 in concrete construction, adjustable with RC material for reducing corrosion problem and enhancing oxidization process of volatile organic compounds (VOC).

Index Terms—Carbonation, corrosion, photo catalytic material, reinforced concrete.
