Alkali activation of fayalite slag

, 2017
In this thesis, alkali activation of fayalite slag was investigated. The slag utilized is a waste by product from nickel production, the activation of which resulted in the formation of a geopolymer binder of acceptable properties. The need for a reduction in overall waste output as well as the cementitious properties exhibited by this slag motivated ...

Performance, thermodynamic modelling, and global warming potential of low sodium-activated artificial granulated slag substituted with quartz and limestone fillers

Cleaner Engineering and Technology
Commercialization of alkali-activated slag faces, among others, two major hurdles: limited availability of blast-furnace slag and the high cost of alkaline activators.

Investigation of shrinkage mechanism of alkali-activated slag

Case Studies in Construction Materials
Slag is a highly active waste product that can be added to alkali-activated cement to improve their mechanical properties, but also creates significant shrinkage, which limits its usefulness. This study examines the reasons behind the shrinkage of alkali-activated slag (AAS).

Alkali-activated metakaolin-blast furnace slag blends: a state-of-the-art review on early-age properties, mechanical properties and durability

Reviews on Advanced Materials Science
The engineering properties of alkali-activated materials (AAMs) are closely related to the selection of precursors. Alkali-activated metakaolin-blast furnace slag blends (alkali-activated MK-BFS blends) takes full advantage of the potentially ...
