Both the autogenous and drying deformations of AAM are significantly higher than those of ordinary concrete. Even though much research has been performed on this topic, the exact mechanisms at the origin of these increased deformations are still not well understood. In particular, the knowledge of the macroscopic deformations of AAM and its nano-and microstructural origin still needs to be improved. Two main volume stability aspects will therefore be studied, related respectively to the autogenous deformations and to the drying behaviour.

Volume stability in autogenous conditions

  • Mechanisms of the high autogenous deformation
  • Effect of temperature on the autogenous deformation
  • Empirical and numerical modelling strategies adapted to AAM deformation
  • Cracking potential of AAM due to the restrained deformations

Volume stability in drying conditions

  • Mechanisms of the water transport during drying
  • Local assessment of the moisture content
  • Tools for analysing the drying deformation of AAM
  • Cracking potential in restrained drying conditions
