This 3rd RILEM Workshop on the processes involved in the transport of chloride ions through concrete has highlighted the still prevailing distance from present knowledge to the attempts to predict the time to depassivation of steel reinforcement in real reinforced concrete structures exposed to service conditions containing chloride ions. The more experimental results are published the clearer the huge task appears of what an analytical modelling of the chloride transport into concrete represents.
The workshop was focused on in-depth discussions around six main lectures summarizing the state of the art. The lectures and the oral contributions enabled the participants to reach conclusions stimulating new research and new empirical ways to provide assistance and solutions to engineers designing new structures and assessing existing ones.
Six subjects were selected for presentation in key note lectures and they were given by the following experts:
1. Concepts on chloride ingress modelling – L.O. Nilsson
2. Concepts on diffusion coefficients – C. Andrade
3. Threshold chloride levels – C. Page
4. Surface concentration and calculated D in existing structures – C. Larsen
5. Short term testing for long term prediction – M. Thomas
6. What a service life model can offer to an owner – J. Gulikers
Not all of the key note lectures are published in the present volume of the workshop proceedings, but a summary of the major ideas has been prepared by the secretary of RILEM TC 178-TMC, Prof. Dr. Kropp.
The recognition of the limited scientific knowledge and therefore of the uncertainty inherent in any type of model has to be considered as a stimulation of further research and a growing importance of the subject. However, all interested researchers and practitioners should approach the modelling of chloride penetration into concrete with the modesty necessary to face scientific challenges instead of demanding accuracies in the prediction that are unachievable at present.
