Novel Experiments on Cement Yield Concrete Results

Caption

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 adsorbed on the surface; pale blue areas represent liquid water caught in nanopores.
