Modeling of Thermomechanical Effects of Alkali-Silica Reaction

In this paper, a nonlinear continuum theory is applied to model the thermomechanical behavior of concrete subjected to alkali-silica reaction. The reaction results in formation of silica gel around the aggregate particles, which expands triggering a progressive damage of the material. The expansion rate is assumed to be controlled by the alkali content, the magnitude of confining stress as well as the evolution of the temperature. The progress …
