Structural characterization of C–S–H and C–A–S–H samples—Part II: Local environment investigated by spectroscopic analyses

Spectroscopic studies (1H, 23Na and 27Al MAS NMR and Raman spectroscopy) have been used to characterize three series of C–S–H samples (0.8

The insertion of aluminum atoms into the C–S–H structure has been investigated by spectroscopic analyses (27Al and 1H MAS NMR and Raman). The previously determined structural continuity, when increasing the C/S ratio from the C–S–H(I) type to the C–S–H(II) type, has been confirmed even in the presence of aluminum.Figure optionsDownload as PowerPoint slide
