Etude expérimentale et modélisation de l'influence de l'eau sur la réaction alcali-silice

ABSTRACT Water is very important for alkali-silica reaction, it is the diffusion medium for ionic species and in the same time it is part of the reaction products. The work presented in the following article deals with a new method which takes into account the effect of water on alkali-aggregate reaction thanks to original laws. The latter have been determined thanks to experimental results. The modelling is validated by the means of numerical simulations of experiments carried out on purpose or taken from litterature.
