Influence of the composition of cement kiln dust on its interaction with fly ash and slag
TLDR
In this paper, the performance of two different CKDs as components in a novel binder is evaluated, and Ettringite and calcium aluminosilicate hydrate (C-A-S-H) are identified as the main hydration products in the hardened binder system.About:

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
Factors affecting the strength of alkali-activated slag
TL;DR: In this article, the effect of several factors on the strength of alkali activated slags has been investigated, and the optimum range for each factor is suggested through reviewing previous work and their recent results of a full factorial range strength study.
