AbstractDynamic mechanical analysis measurements were made on the following calcium-silicate- hydrate systems: 1.4 nm tobermorite (T), jennite (J), synthetic C-S-H (C/S = 0.80, 1.20 and 1.50) and cement paste. The age of the cement paste varied from 3 days to 45 years. Plots of storage modulus versus porosity were constructed for all these materials. The non-uniqueness of the curves is discussed with reference to Taylor's analysis of strength-porosity curves and the influence of particle type, density and crystallinity. Additional insights regarding the practical application of T-J and T-CH nanostructural models for the C-S-H nanostructure in hydrated cements is provided. © 2012 RILEM.
