Abstract
The alkali-silica reaction (ASR) is a long-term deterioration process, which produces a hydrophilic and expansive gel causing damage. The ASR acts on concrete as an ageing phenomenon, modifying the material on the basis of its stress state. Focussing on the mechanical degradation of concrete, estimated trends for the mechanical properties in free expansive affected concrete arepresented. These show the result of recent research which collected and statistically analysed laboratory tests on 54 concrete mixes performed by 11 authors. Comparable findings are also obtained through a multiscale material model, which aims to capture the micro and macro aspects of the problem. The ASR-affected concrete is seen as an evolving material, whose state should be followed over time taking into account chemomechanical coupling.
