Data from: Nanoindentation creep of synthesized calcium-(alumino)-silicate-hydrate

The long term dimensional stability of concrete is crucial to long-lasting
infrastructure and the primary binding phase (calcium-silicate-hydrate) is
thought to be the primary phase responsible for viscoelastic behavior.
Previous research indicates that the molecular structure of
calcium-silicate-hydrate plays a role in viscoelastic behavior and is
modified by changing the chemical composition, including the addition of
aluminum into the structure. In this study,
calcium-(alumino)-silicate-hydrate is synthesized with different molecular
structure and tested for viscoelastic behavior using creep nanoindentation
methods. The data presented here are used to support the conclusion that
micro-sliding of calcium-(alumino)-silicate-hydrate sheets relative to
each other at interlayer sites is a source of viscoelastic behavior and
that increased bonding and ionic correlation forces across the interlayer
reduce the amount of time-dependent deformation. Supporting data include
creep nanoindentation (load, displacement, and time), thermogravimetric
analysis (temperature and weight loss), x-ray diffraction (diffraction
angle and intensity), and solid-state nuclear magnetic resonance
spectroscopy (chemical shift and intensity) for four different specimens
with different molecular structures/chemical compositions.
