Abstract
The mesomechanical model for concrete previously developed for purely mechanical
actions, is used as the basis for coupled durability mechanics calculations. Until now,
the phenomena studied include drying shrinkage, external sulfate attack and
mechanical effects of high temperatures. On-going work is focusing on alkali-silica
reaction (ASR). From the chemical viewpoint, ASR is represented with a three-field
diffusion-reaction chemical model, which is shown to qualitatively and quantitatively
reproduce some experimental measurements of sandwich-type specimens subject to
standardized accelerated ASR tests. The model developed includes the recently
identified role of Calcium in this type of expansive reactions.
