Titre : Influence of the spatial variability of leaching kinetics parameters on the lifespan of a concrete structure Type de document : texte imprimé Auteurs : Thomas de Larrard, Auteur ; Benboudjema, Farid, Auteur ; Jean-Baptiste Colliat, Auteur Année de publication : 2012 Article en page(s) : pp. 606-624 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Leaching Porosity Tortuosity Variability Distribution Correlation length Karhunen--Loève expansion Monte Carlo method Résumé : This works aims at studying, through the Monte Carlo method, the influence of the leaching kinetics parameters spatial variability on the lifespan of a concrete structure. The considered structure is a tunnel for nuclear waste storage. It is observed that the expected value for the lifespan estimated when considering the material spatial variability is significantly lower than the lifespan estimated with a single simulation considering uniform parameter fields, equal to the expected value for each parameter.

Titre : Modelling the influence of temperature on accelerated leaching in ammonium nitrate Type de document : texte imprimé Auteurs : Thomas de Larrard, Auteur ; Stéphane Poyet, Auteur ; Magalie Pierre, Auteur Année de publication : 2012 Article en page(s) : pp. 322-335 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Leaching Temperature Ammonium nitrate Thermoactivation Résumé : This study proposes two models for accelerated leaching in ammonium nitrate under variable temperature. The first approach assumes a thermoactivated linear relationship between degradation and the square root of time. The second approach introduces, within a phenomenological model, the thermoactivation of diffusion and hydrates solubility. These two approaches enable one to analyse accelerated leaching tests to identify the concrete variability in order to get rid of the influence of temperature.

Both phenomena are coupled for the estimation of the damage time evolution. Simulations are achieved so as to quantify the influence of the input parameters variability on the structure lifespan. The most influent parameters are identified and threshold values for lifespan classification are enlighted.
