Title: Novel Experiments on Cement Yield Concrete Results
Description: Schematic drawing of nanoscale calcium silicate hydrate (C-S-H) particles in cement showing the multiple roles played by water as defined in the NIST/Northwestern experiments. Solid red areas are calcium silicate, pebbled areas in between show the water physically bound between the layers to form solid C-S-H. Dark blue halos around the C-S-H particles are water chemically adsorbed on the surface, pale blue areas represent liquid water caught in nanopores.

*MSEL, nanoscale calcium-silicate-hydrate, cement
