In this paper, a mechanical behavior model for concrete undergoing Alkali-Silica Reaction (ASR) expansions is presented. The relation between evolution of expansions and external pressure is specifically taken into account in the model, including a procedure to calculate inhibition pressure (defined as the compressive stress threshold beyond which no expansion can take place) from experimental data...
Availability of computational power calls for the responsible use of mechanical models that faithfully represent material behavior even in complex cases, as is concrete undergoing Alkali–Silica Reaction (ASR) expansion. In this paper, a series of tests aimed towards obtaining meaningful data for mechanical characterization of an existing, old-aged, ASR-affected dam concrete are presented. These tests,...
