Abstract:Physicochemical processes, such as thermal effects, fluid transfer, and alkali-aggregate reaction, can induce expansion, damage, and cracking of concrete structures. Maintenance and repair are costly on the one hand, and the prediction of service life is still difficult on the other. A mechanical model (for characterizing the degradation of concrete) using the thermodynamics of irreversible processes is presented. The state of concrete as a material is described by different variables for damage, mass transfer, alkali, and temperature. The choice of variable depends on the physicochemical process and volume of the concrete structure considered. To justify the modeling, major hypotheses must be discussed. This model has already been applied to a gravity dam, and a good relationship between predicted and actual damage induced by thermal effects has been obtained.
