Multiscale experimental characterization of ageing basic creep of VERCORS concrete
Résumé
Creep and shrinkage of concrete are the main mechanisms responsible of prestress losses experienced by prestressed concrete structures, such as containment buildings of nuclear power plants. Relevant and reliable models of the concrete delayed strains are thus of paramount importance for the long term operation of such structures. To improve understanding of this delayed behavior and also to constitute a comprehensive validation dataset for these models, an experimental campaign has been setup and conducted. The latter focuses on autogeneous shrinkage and basic creep. The originality lies in both the multiscale nature of the campaign and the multiple loading ages considered for creep tests.
