Abstract : In this paper, we discuss the alternative interpretation of NMR spectra from (i) “Structural characterization of geomaterial foams—Thermal behavior” by Prud'homme et al. published in Journal of Non-Crystalline Solid, 2011, and from (ii) the reply proposed by J. Provis and S.A. Bernal in this journal. In this contribution, other alternatives for the NMR bands assignment are discussed and compared with infrared spectroscopy and thermo-gravimetric results since closed relationship between NMR-IR-TG is effective. In agreement with these authors, the analysis of prepared foams requires additional work addressed to detect the presence of two phases with different tetrahedral condensation. Relative arrangement of these two phases could affect in a significant way the physical chemical properties of prepared foams.
