Abstract: Calcium silicate hydrates exhibit various mesotextures, composed of fundamental pieces presenting with different morphologies. The structuration of nanolayer (2D) and nanofibrillar (1D) materials is a result of the interplay between intermolecular forces involving the fundamental pieces (layers or fibrils) and the pore fluid as well as the flexibility of each piece. In this paper, coarse-grained simulations are performed to simulate the differences in the
mesotexture of crystalline calcium silicate hydrate with a fibril morphology taking into account the flexibility of these fibrils. The resulting pore size distributions of the gel are computed and exhibit a dependence on the size of the fibril. These results are a contribution to a better understating of C-S-H nanostructuration.
