Figure 2: These figures show stiffness and hardness of cement hydrate at various packing fractions as measured by nanoindentation in three laboratory samples (small symbols) and calculated in a simulated sample generated by the researchers’ model (yellow squares). The simulation results match the experimental data well. The computed results extend down to packing fractions that produce material too soft to be tested experimentally.
