Creep of Bulk C-S-H: Insights from Molecular Dynamics Simulations
Understanding the physical origin of creep in calcium-silicate-hydrate (C-S-H) is of primary importance, both for fundamental and practical interest. Here, we present a new method, based on molecular dynamics simulation, allowing us to simulate the long-term visco-elastic deformations of C-S-H. Unde...

| Resumo: | Understanding the physical origin of creep in calcium-silicate-hydrate (C-S-H) is of primary importance, both for fundamental and practical interest. Here, we present a new method, based on molecular dynamics simulation, allowing us to simulate the long-term visco-elastic deformations of C-S-H. Under a given shear stress, C-S-H features a gradually increasing shear strain, which follows a logarithmic law. The computed creep modulus is found to be independent of the shear stress applied and is in excellent agreement with nanoindentation measurements, as extrapolated to zero porosity. |
