A probabilistic approach for modelling calcium leaching in concrete structures

T. de Larrard, F. Benboudjema & J.-B. Colliat J.-M. Torrenti

ABSTRACT: This project aims at investigating the concrete properties variability and its influence on the long-term behaviour of structures. For this purpose, a model for calcium leaching under variable temperature is developed and validated. Simultaneously an important experimental campaign is carried out to follow up two real building operations. An inverse analysis tool is developed to identify the non-measurable parameters of diffusion.
