摘要: Moisture transfers have a major effect on concrete durability. For Alkali-Silica Reaction (ASR), chemical swellings depend water content, and drying can important consequences. Within the framework of large experimental study developed in partnership by Laboratoire Central des Ponts et Chaussees (LCPC) Electricite de France (EDF), continuous measurements moisture transfer reactive structures was one main purposes. This paper deals with data bank absorption, measured six 3 m long beams weighing gammadensitometry devices specially designed for this study. These enable some quantitative conclusions to be reached. Moreover, allows validation models representing mass variation time beams. Profiles variations thus obtained are mandatory first step calculations estimate mechanical behaviour these reference or ASR damaged
