Keywords: Novel Experiments on Cement Yield Concrete Results (5887834848).jpg 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 Credit NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5887834848/ Novel Experiments on Cement Yield Concrete Results 2007-03-28 11 55 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5887834848 2016-09-07 02 34 04 United States Government Work Uncategorized 2016 September 20 |
