Journal ArticleDOI
The role played by the reactive alumina content in the alkaline activation of fly ashes
TL;DR: In this paper, the authors explored the relationship between the chemical composition of fly ashes and the microstructural characteristics and mechanical properties of the cementitious materials resulting from the alkali activation of fly ash (AAFA) and found that the amount of reactive aluminium plays an important role in the aluminosilicate gel formation.
Journal ArticleDOI
Alkaline Activation of Fly Ashes: NMR Study of the Reaction Products
TL;DR: In this paper, reaction products formed during alkaline activation, with 8M NaOH solutions, of fly ashes have been characterized with 29Si and 27Al magic-angle spinning nuclear magnetic resonance (MASNMR) spectroscopy.
Journal ArticleDOI
Structure of Calcium Silicate Hydrates Formed in Alkaline-Activated Slag: Influence of the Type of Alkaline Activator
TL;DR: In this article, the influence of the alkaline activator (NaOH, waterglass, or Na2CO3) on the structure of the hydrated calcium silicate formed in alkali-activated slag (AAS) cement pastes has been investigated by FTIR, 29Si and 27Al magic-angle scattering nuclear magnetic resonance, and TEM/EDX techniques.
Journal ArticleDOI
Aluminum-27 and Silicon-29 Magic-Angle Spinning Nuclear Magnetic Resonance Study of the Kaolinite-Mullite Transformation
TL;DR: The 27Al and 29Si NMR signal analysis of samples heated above 400°C demonstrates that the tetrahedral sheet of kaolinite begins to break down near 600°C and continues to do so to 900°C as discussed by the authors.
Journal ArticleDOI
Effect of the SiO2/Na2O ratio on the alkali activation of fly ash. Part II: 29Si MAS-NMR Survey
TL;DR: In this paper, the degree of polymerization of the predominant silica species in the activation solutions plays an important role in the kinetics, structure and composition of the gel initially formed.
