One-part alkali-activated materials : a review (2018, background): “Using blast furnace slag improves the reactivity of low‐calcium-content fly ash [41].”
Quantitative study of the reactivity of fly ash in geopolymerization by FTIR (2012, background): “This can be inferred from consideration of the dissolution mechanism of fly ash, where Si and Al oligomers are dissolved from the surface of the particles in contact with alkaline solution [18].”
A physico-chemical basis for novel cementitious binders (2011, background): “Indeed, the increased reactivity and performance of Class F fly ashes associated with higher alumina contents as reported by Duxson [29,51] is likely to be associated with an increase in the number of ”reactive” – Al–O–Si- linkages in the aluminosilicate glass.”
X-ray microtomography shows pore structure and tortuosity in alkali-activated binders (2012, background): “The unreacted GGBFS and fly ash particles are readily distinguished by their geometry; fly ash is comprised of polydisperse spherical particles, whereas GGBFS is visible as irregular jagged particles [6].”
Mechanical property and structure of alkali-activated fly ash and slag blends (2012, background): “The most common aluminosilicate materials used for synthesizing geopolymer binders include calcined clays (metakaolin) and industrial wastes (fly ash and slag) [13].”
Compressive strength and microstructural characteristics of class C fly ash geopolymer (2010, background): “Compositionally, CFA can be viewed as resting somewhere in between FFA and GGBFS [9].”
Role of carbonates in the chemical evolution of sodium carbonate-activated slag binders (2015, background): “The microstructure, and therefore the performance, of alkali-activated slag materials is strongly dependent on factors such as the chemistry and mineralogy of the slag precursor, the type and concentration of the alkali-activator and the curing conditions [5–10].”
Using fly ash to partially substitute metakaolin in geopolymer synthesis (2014, positive): “However, as not all fly ashes are highly reactive (Duxson and Provis, 2008), it is often desirable to blend fly ashes with other geopolymer precursors in designingmixeswith acceptable strength andmicrostructural development rates.”
