摘要：

The experimental results of isotropic compression tests performed at 20 degrees C and 90 degrees C on a class G hardened cement paste hydrated at 90 degrees C (Ghabezloo et al., 2008, Cem. Conc. Res. 38,1424-1437) have been revisited considering time-dependent response. Within the frame of a viscoplastic model, the non-linear responses of the volumetric strains as observed in drained and undrained tests and of the pore pressure in undrained tests are analysed. The calibration of model parameters based on experimental data allows to study the effect of the test temperature on the viscous response of hardened cement paste showing that the creep is more pronounced for a higher test temperature. The effect of the hydration temperature on the time dependent behaviour is also studied by evaluating the model parameters for a cement paste hydrated at 60 degrees C. The time-dependent deformations are more pronounced for hydration at a higher temperature. (C) 2012 Elsevier Ltd. All rights reserved.
