Proceedings pro019 : 2nd International RILEM Workshop on Testing and Modelling the Chloride Ingress into Concrete

From the first workshop on Chloride Penetration in Concrete organised by RILEM in October 1995 a lot of new information has been generated in this field of research.
Numerous papers have been published presenting the development of the basic solution (so named "errror function") of Fick's second law and its application to predict the time to depassivation of the steel reinforcement. However, new evidences from results on existing structures indicate that real behaviour does not follow always this kind of modelling and that, much more work is necessary, if the basic knowledge generated in the laboratory is liked to be used in the calculation of service life of concrete structures.

This second workshop has provided a platform for an exchange in on-going research and development in the field of modelling the performance of reinforced concrete structures under the attack of chloride ions. Amongst the various damage mechanisms related to chloride attack the workshop focused in problems of corrosion of reinforcements.
It was structured in four parts:
1) Description of the fundamental processes of chloride penetration into concrete.
2) Model the chloride ingress into concrete.
3) Testing of the chloride transport parameters.
4) Chloride threshold concentration.
