Modélisation physico-chimique de la réaction alcali-granulat: apport au calcul des structures dégradées
Alkali-aggregate reactions are heterogeneous chemical reactions randomly distributed inside concrete. Now, there is a need in modelling of such reactions in order to make structural calculus. A multi-scale description of the phenomena is described. In a first local approach, mechanical effects are described by taking into account the elementary chemical reactions and the random distribution of size and number of reactive sites. Swelling due to the chemical reactions results from this modelling. In a second approach, in order to make structural calculus, local informations are used in a more global modelling capable to describe induced mechanical effects due to alkali-aggregate reactions in real structures.
