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.

Fly ash based alkali activated cements low heat evolution materials [PDF]
, 2013 Hardening of concrete is supported by heat emission due to the cement hydration processes.Rising of temperature leads to stresses because of irregular heating and cooling so as interna! layers are cooling slowly When a large thermal stresses are occurred
