Geopolymer technology: the current state of the art
Peter Duxson,Ana Fernández-Jiménez,John L. Provis,Grant C. Lukey,Ángel Palomo,J.S.J. van Deventer +5 more
TL;DR: A brief history and review of geopolymer technology is presented with the aim of introducing the technology and the vast categories of materials that may be synthesized by alkali activation of aluminosilicates as mentioned in this paper.
Journal ArticleDOI
Composition and Microstructure of Alkali Activated Fly Ash Binder: Effect of the Activator
TL;DR: In this paper, the relationship between the mineralogical and microstructural characteristics of activated fly ash mortars and its mechanical properties has been established, and the results of the investigation show that in all cases (whatever the activator used) the main reaction product formed is an alkaline aluminosilicate gel, with low-ordered crystalline structure.
Journal ArticleDOI
Compatibility studies between N-A-S-H and C-A-S-H gels. Study in the ternary diagram Na2O–CaO–Al2O3–SiO2–H2O
TL;DR: In this article, the compatibility relationship between C-A-S-H and N-Aluminum-modified calcium silicate hydrate (C-A,S,H) gels is assessed.
Journal ArticleDOI
Microstructure Development of Alkali-Activated Fly Ash Cement: A Descriptive Model
TL;DR: In this paper, the microscopic study of a set of alkali-activated and thermally cured fly ash samples enabled the authors to establish a descriptive model for the microstructural development of fly ash-based cementitious geopolymers.
Journal ArticleDOI
Characterisation of fly ashes. Potential reactivity as alkaline cements
TL;DR: In this article, a representative group of Spanish fly ashes has been characterised in order to determine its capacity for being alkali activated and give place to a material with cementitious properties.
