Title: International RILEM Workshop on Integral Servie Life Modelling of Concrete Structures Edited by R. M. Ferreira, J. Gulikers, C. Andrade ISBN: 978-2-35158-058-5 e-ISBN: 978-2-35158-090-5 Pages: 458 Publication date: 2007 |
Modelling of chloride penetration and carbonation has attracted a great deal of attention in recent years; however, essential aspects such as the chloride threshold still remain controversial. Corrosion leads to several undesirable effects, for example, cracking and spalling of the concrete cover, loss of steel/concrete bond and reduction of the loadbearing capacity of the structure. So far, most of the structural consequences of reinforcement corrosion have been scarcely treated in a rigorous manner. Therefore, modelling of the overall structural performance after corrosion initiation is an important aspect to be considered by the RILEM Technical Committee - Model Assisted Integral Service Life Prediction of Concrete Structures with respect to Reinforcement Corrosion (TC 213-MAI).
An integrated approach seems to be the indicated methodology to be followed. On the other hand, modelling can be assisted by testing of a particular concrete or by monitoring using external techniques and embedded sensors. The objective of RILEM TC 213-MAI is the preparation of a State of the Art Report on currently available models for both the initiation and propagation stages of reinforcement corrosion in concrete structures, as well as a compilation of relevant tests and sensors suitable for supporting such models. Another objective is the preparation of a RILEM Recommendation for users of service life models.
The main topics addressed in the workshop in order to finalize the State-of-the-Art Report were:
a) Penetration of aggressive substances from a particular exposure environment, either for new structures (design stage), or for existing structures (during service);
b) Depassivation process and the subsequent electrochemical process of reinforcement corrosion, once it has been initiated;
c) Structural behaviour following corrosion initiation (cracking, spalling, loss of cross sectional area, debonding, deflection, collapse etc);
d) Monitoring of the reinforcement corrosion by external techniques or embedded sensors.
Target readers: graduate students, material scientists, researchers, engineers, material suppliers, contractors and scientists from research organizations, universities and industries
