Abstract: Deterioration of reinforced concrete structures due to carbonation-induced corrosion is a significant problem. As a result, several significant researches were performed in recent decades for understanding the mechanisms and determining effective measures to control it. In urban areas, where environmental pollution results in considerable concentration of carbon dioxide, carbonation of concrete in structure takes place. In the case of carbonation, chemical reaction between carbon dioxide from air and the hydration products of cement in concrete causes reduction in the alkalinity of concrete and consequently reduce its ability to protect the steel from corrosion. This paper reviewed several researches on carbonation of concrete, describes the different methods for determining the carbonation state, describes carbonation curing method for reducing carbonation rate and enhancing the characteristics of concrete.

Keywords: concrete; corrosion; carbonation; deterioration; curing.
