Interaction between salts (NaCl, CsCl) and calcium silicate hydrates (C-S-H)
Article Abstract:
The interaction of sodium and cesium chloride salts with calcium silicate hydrates (C-S-H) was investigated using solid-state nuclear magnetic resonance spectroscopy. Results showed that Cs+ and Na+ have a liking for the C-S-H surface, but each behave differently due to their different hydration energy. Moreover, the cations may be located in a diffuse ion swarm in hydrated C-S-H, but would form outer-sphere complexes in dry C-S-H.

Application of (super 29)Si homonuclear and (super 1)H-(super 29)Si heteronuclear NMR correlation to structural studies of calcium silicate hydrates
Article Abstract:
Homonuclear and hetronuclear solid-state NMR methods are applied for the investigation of C-S-H. Double quantum homonuclear (super 29)Si-(super 29)Si correlation are applied using the BAck to BAck recoupling scheme to gain information about connectivity between silicates and 2D (super 1)H(super29)Si HETeronuclear chemical shift CORelation (HETCOR) to characterize the proton environment of the silicate chains.

Aluminum incorporation in calcium silicate hydrates (C-S-H) depending on their Ca/Si ratio
Article Abstract:
Research is presented demonstrating the characterization of the aluminium incorporation in calcium silicate hydrates' tetrahedral-octahedral-tetrahedral structure. Aluminium magic angle spinning nuclear magnetic resonance spectroscopy is used at various magnetic fields.
