ironic

NMR and Infrared Spectroscopies of C-S-H and Al-Substituted C-S-H Synthesised in Alkaline Solutionsed soda solutions. The stoichiometry and spectroscopic characteristics of samples have been studied by FTIR, .A1 and .Si MAS NMR spectroscopies. The structural changes induced by substitutions have been discussed on the basis of the dreiketten structure of the tobermorite silicate chains.

nurture

Thermochemical and Macromolecular Approach of the C-S-H Structurerometry conditions, is suggested. The elementary act of the pozzolanic reaction leads to an equality between the number of Ca atoms and the hydroxylic H.O. The hexa-coordination of Ca. leads to two supplementary molecular H.O per Ca.. This model is applied to the different basic structures Q. and a scheme is proposed for each of them.
