Matthieu Briffaut, Auteur ; Benboudjema, Farid, Auteur ; Torrenti, Jean-Michel, Auteur |At early age, temperature in massive concrete structures may reach over 70°C because hydration is an exothermic chemical reaction. Temperature evolution (increasing followed by decreasing temperature) can lead to damage risks in the short and lo[...]

Thomas de Larrard, Auteur ; Benboudjema, Farid, Auteur ; Jean-Baptiste Colliat, Auteur |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 obs[...]

Benboudjema, Farid, Auteur ; Meftah, Fékri, Auteur ; Torrenti, Jean-Michel ; Sture, Stein, Éditeur scientifique |Predicting delayed strains in concrete proves to be critical to a large number of prestressed concrete structures. These delayed strain include drying shrinkage, basic, and drying creep strains essentially. In this paper, a model for identifying[...]

Thomas de Larrard, Auteur ; Benboudjema, Farid, Auteur ; Jean-Baptiste Colliat, Auteur |We introduce a model for calcium leaching and creep strain evolution. 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[...]
