Applicability of natural abundance 33S solid-state NMR to cement chemistry
Résumé
With the development of high-magnetic field spectrometers, 33 S solid-state NMR is now clearly feasible but remains complex, especially considering the low sensitivity of 33 S NMR. This communication briefly explores the potential of 33 S NMR in the field of cement chemistry. Based on a few significant examples such as the one of ettringite, whose sulfur NMR spectrum is reported here for the first time, it appears that 33 S solid-state NMR might be able to distinguish between the sulphates present in a cement paste taking advantage of both the chemical shift and the quadrupolar interaction.
