The steel reinforced concrete became the most widely used structural material in the world because of its economical, strength and durability properties. Steel-reinforced concrete structures were viewed as maintenance-free and unlimited service life until the mid-1970s. Conversely, since then, several durability associated problems have emerged, such as alkali- silica reactions, sulphate attacks and corrosion of steel reinforcement. Among all durability related problems in steel-reinforced concrete structures, corrosion of steel reinforcement has been recognized as one of the main source of deterioration.
The principal causes of steel corrosion in concrete are chloride attack and carbonation. These two aggressive agents usually do not attack the concrete integrity but pass through concrete pores and attack the steel reinforcement. Acids and other aggressive agents such as sulphate deteriorate the concrete properties first then affect the steel reinforcement. Therefore, most of the chemical attacks are concrete problems before steel corrosion problems; and chloride ions and carbon dioxide destroy the steel without considerably damaging the concrete.
