| Abstract | Mechanisms of creep of hydrated Portland cement paste are reviewed with reference to the role of water. The coupling of an a.c. impedance analyzer with a miniature loading system was used to follow real-time microstructural changes due to sustained load. Various pre-drying treatments (including use of solvent exchange methods) were used to probe the sensitivity of the creep process to microstructural change and the presence or absence of moisture. Characterization of the water in the paste was carried out using a controlled environment differential thermogravimetric technique. Evidence suggests that the presence of water is not an 'à priori' condition for creep. A creep mechanism involving microsliding between C-S-H sheets appears to be compatible with the experimental evidence. |
