Composition and Microstructure of Alkali Activated Fly Ash Binder: Effect of the Activator
1K
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.
