Description
  • Creep in mature and hardening cement paste is micromechanically predicted from the viscoelastic behavior of C-S-H. A powerful numerical homogenization method based on fast Fourier transform is formulated and used with evolving digital cement microstructure at the resolution of 1 um. The constitutive equation of C-S-H is based on B3 model. Analysis of a two-year old cement paste revealed negligible irreversible deformation at saturated conditions after unloading. The micromechanical simulation of young and hydrating cement pastes with solidifying C-S-H revealed complex nature of creep. In order to match experimental data of young hydrating cement paste, the capillary water had to be deactivated and the assumptions of perfect bonding and elasticity of non-creeping solids seem to be valid only partially.
