MAS-NMR spectroscopy of calcium aluminosilicate hydrate

by Leslie J. Struble, Department of Civil and Environmental Engineering, University of Illinois at Urbana-Champaign

Calcium aluminosilicate hydrate is the principal binding phase in hydrated portland cement. Because it is not well crystalline x-ray diffraction provides only limited information, but its molecular structure can be characterized using solid-state 29Si NMR. This presentation will provide background on the structure of this phase as well as background on solid-state NMR analysis, then show
