- A review: The comparison between alkali-activated slag (Si + Ca) and metakaolin (Si + Al) cements (2010, background): “Lecomte [55] compared the microstructure between geopolymers, alkali-activated slag cement and Portland cement, and 29Si MAS-NMR spectroscopy has confirmed that in Portland cement, CSH gel contains silicate groups organised in linear finite chains of “dreierketten” structure, thus mainly SiQ1 and Si”
- Hardening evolution of geopolymers from setting to equilibrium: A review (2020, background): “This expectation has been demonstrated for MK-based geopolymers with incorporated Ca(OH)2 [122].”
- Apply 29Si, 27Al MAS NMR and selective dissolution in identifying the reaction degree of alkali activated slag-fly ash composites (2017, background): “The high calcium systems usually result in a reaction product of tobermorite-like C-A-S-H gel with a low Ca/Si ratio and a high Al content [8], while the major product for Si + Al systems is a three-dimensional N-A-S-H type gel [9].”
- Alkali activation of metakaolins: parameters affecting mechanical, structural and microstructural properties (2007, methodology): “It has been concluded from FTIR, 27 Al, 29Si MAS NMR and 23Na MAS NMR [7] studies that its three-dimensional structure is a network [Q4(Al)] consisting in alternating SiO4 and AlO4 tetrahedra linked by shared O atoms [ 7 ,13].”
