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 ...

Chloride ingress through alkali activated slag concretes

, 2014
Alkali activated slag (AAS) is a credible alternative to Portland cement (PC) based binder systems. The superior strength gain and low embodied carbon make it a potential binder for next generation concretes.

Hybrid fly ash based alkali activated cements [PDF]

, 2013
Alkaline activation is one of the most perspective ways for creating very high volumes fly ash cements. The main phases of structure in such “hybrid” systems are represented by mixes N-A-S-H and N-C-A-S-H new formations.
