| Abstract | The effect of three pre-drying treatments (prior to re-saturation with synthetic pore fluid) on time dependent deformation was investigated. The pre-drying treaments comprised methanol and isopropanol exchange (followed by vacuum heating at 37°C) and vacuum drying at 37°C alone. Real-time changes in microstructure due to sustained load were followed through the coupling of an a.c. impedance frequency analyzer with a miniature loading system. Cement paste specimens were in the form of T-shaped columns with minimum thickness value around 1 mm. The impedance analysis included an assessment of the relevance of the high frequency arc depression angle to creep and shrinkage behavior of cement paste. |
