DESCRIPTION:Creep is a fundamental component of concrete mechanical behavi
 or\, especially regarding civil engineering structures involved in electri
 city production.\nThis presentation proposes a few insights on concrete cr
 eep modeling from physical processes.\nFirst\, a morphological model of hy
 drating cement paste is developed and validated on stiffness measurements.
  Special attention is paid to the evolving nature of the microstructure. S
 econd\, this model is extended to basic creep\, where ageing stems from th
 e ongoing hydration reactions. The challenges associated to building a mic
 romechanical model of a microstructure-evolving material\, in the framewor
 k of viscoelasticity\, are overviewed. Third\, a few other examples\, beyo
 nd creep\, of application of micromechanics to engineering issues are brie
 fly presented.\n
