The objective of this state of the art report is to describe the proven and generally accepted processes of corrosion of the reinforcement and its protection against corrosion, and to discuss current problems. The report concentrates on normal corrosion processes relevant for steel in concrete. Hydrogen embrittlement and stress corrosion cracking of prestressed steel is not covered. Chapter 2 provides a basic description of the corrosion mechanisms of metals in solutions with special reference to the corrosion of steel in concrete. On this basis the processes leading to depassivation of the reinforcement and the mechanisms decisive for the corrosion process itself are tackled in more detail in Chapters 3 and 4. Measures used to protect the steel reinforcement are described in Chapter 6. Advice on the optimum mix design, composition, and curing regime of the concrete to prevent corrosion is provided. Additional measures, such as the use of corrosion inhibitors or metallic and organic coatings, the application of corrosion resistant alloys, and cathodic protection are also described. An overview on corrosion monitoring techniques is given in Chapter 6, and recommendations for further research in Chapter 7. (TRRL)
