The Effect of Undrained Heating on a Fluid-saturated Hardened Cement Paste

The effect of undrained heating on volume change and induced pore pressure increase is an important point to properly understand the behavior and evaluate the integrity of an oil well cement sheath submitted to rapid temperature changes. This thermal pressurization of the pore fluid is due to the discrepancy between the thermal expansion coefficients of the pore fluid and of the solid matrix. Equations governing the undrained thermo-hydro-mechanical response of a porous material are presented and the effect of undrained heating is studied experimentally for a saturated hardened cement paste. The measured value of the thermal pressurization coefficient is equal to 0.6 MPa/°C. The drained and undrained thermal expansion coefficients of the hardened cement paste are also measured in the heating tests. The anomalous thermal behavior of cement paste pore fluid is back analyzed from the results of the undrained heating test.
