A multi-scale approach for modelling the structure of cement-based materials has been presented. At each scale of interest, a critical exercise is the validation of the structural models against measured experimental data. Here, this validation has been demonstrated for nanometer level models of the structure of C-S-H gel by comparison against TEM images and measured sorption characteristics. The development of a complete set of representative structural models at all scales of interest should aid greatly in understanding the structure-property relationships present in this complex class of materials.
