Plate I (a) Nanoindentation principle: a diamond nanoindenter is brought in contact with the material of interest
and the force ( P ) and penetration depth ( h ) are monitored continuously. (b) Typical P - h curves for a low-density
(LD) and a high-density (HD) version of C-S-H. Results are from fi nite element simulations.
