Abstract [en]

The present report deals with corrosion of steel reinforcement which is the principal cause of deterioration of reinforced concrete infrastructure. Previous research on steelbar corrosion has mainly been devoted to the causes and mechanisms of corrosionwhile relatively little attention has been given to the problem of assessing the residual strength of corroded structures. The objective of the present report is to investigate the effects of steel bar corrosion on structural performance. In the first phase of this research, a comprehensive evaluation was carried out based on published laboratory testdata on corrosion of steel bars in concrete, see Appendix D. In the second phase, experimental research was conducted to investigate the effects of steel bar corrosion, using both specimens collected from the field (30 years exposure) and standard specimenscast in the laboratory. The experimental data from the present research is used todevelop methods for assessment of the structural consequences of reinforcement corr osion
