INFLUENCE OF CHLORIDES ON THE CORROSION OF STEEL REINFORCEMENT IN CONCRETE

VPLIV KLORIDOV V BETONU NA KOROZIJO JEKLENE ARMATURE

The corrosion of steel reinforcement in concrete due to chlorides has become a major problem for bridge and other concrete structures. Chloride is regarded as an extremely dangerous agent in causing the corrosion of steel reinforcement and also the deterioration of concrete. Chlorides can be present in fresh concrete but they can also permeate into hardened concrete from the environment containing chlorides. A source of chloride in fresh concrete is calcium chloride which is frequently used as a concrete accelerator for the hydration rate. Concrete structures exposed to either sea action or deicing chloride salt represent the typical cases, where chloride ions are not initially present in fresh concrete but subsequently they find their way into hardened concrete by diffusion of the chloride solution. The objective of this article is to briefly review the state of knowledge regarding the action of chloride, with special emphasis on its effect on ordinary steel reinforcement and on the evaluation of chloride limitations.
