Abstract
In the second half of this work, thermal expansion property was systematically investigated for cement pastes with a wide range of microstructure features. It was found that saturated paste behaves anomalouly in response to temperature change, i.e., the thermal expansion is followed by a time-dependent delayed contraction at isothermal condition. This characteristic was found to be related to the pore structure and the elastic properties of the paste. A permeability-based mechanism was proposed to quantitatively explain the observed thermal deformation, and was used successfully to model the delayed contraction and calculate the permeability coefficient of mature, dense cement paste in the order 10 -16 m/s.
