Drained and Undrained Creep of Hardened Cement Paste under Isotropic Loading

The experimental results of isotropic compression tests performed at 20°C and 90°C on a class G hardened cement paste (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...

Summary:The experimental results of isotropic compression tests performed at 20°C and 90°C on a class G hardened cement paste (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 time-dependent response of hardened cement paste.
