Abstract	A multiscale model for shrinkage of cement paste and concrete that links properties at the nanometer, micrometer and millimeter level is proposed. Each parameter of the model at a particular scale level has fundamental physical meaning. The model is used to determine values of shrinkage, bulk modulus, and volume fraction of the constituent phases, and these values are then used to model shrinkage of concrete. Agreement with experimental results is satisfactory and new insight into properties of paste is gained at the micron level.Un modèle multi-échelle pour le retrait de la pâte de ciment et du béton est proposé, qui lie les propriétés aux niveaux nanométrique, micrométrique et millimétrique. Chaque paramètre du modèle à un niveau donné de l'échelle possède une signification physique fondamentale. Le modèle est utilisé pour déterminer les valuers de retrait, de module de compressibilité et de fraction volumique des phases constituantes, et ces valeurs sont utilisées pour modéliser le retrait du béton. La comparaison des résultats expérimentaux est satisfaisante, et un nouvel aperçu sur les propriétés de la pâte est acquis au niveau micrométrique.
