Micro Abstract:
A multiscale micromechanical model for the prediction of the deterioration of concrete caused by Alkali Silica Reaction is presented. The gel pressure results in microcrack growth in the reactive aggregate and the surrounding cement paste. This damage process is formulated in the framework of linear elastic fracture mechanics applied at the scale of the aggregate and the cement paste. The model predictions are compared with selected experimental data.
