With FTIR, the carbonation rate was 30% with identical spectra in C+ and C-. With PND, the width of the diffraction peak (hkl=002) highlighted the anisotropy of nanocrystals (with needle and/or platelet-like shape) along the c-axis with average length of 50 nm and thickness of 10 nm and with no difference between C+ and C- .
