Abstract
NMR spectroscopy is applied to study microstructure of calcium silicat e hydrates present in cement and concrete. It is shown that Si-29 NMR gives information on the siliceous skeleton of the hydrates. H-1 NMR, using CRAMPS techniques, allows to discriminate between protons linked to silicon atoms or to calcium atoms. A first investigation of refere nce compounds indicates that Ca-43 NMR will be powerful to determine c alcium atom sites in the structure. Copyright (C) 1996 Elsevier Scienc e Inc.
