Microstructure, strength, and moisture stability of alkali activated glass powder-based binders (2014, background): “The N–A–S–H gel is formed around the fly ash particles [4,7,13,27], whereas the locations previously occupied by the glass powder are transformed into a sodium silicate gel.”
Impact of curing temperatures and alkaline activators on compressive strength and porosity of ternary blended geopolymer mortars (2018, background): “Incorporation of CaO was shown to affect greatly the GPMs mechanical strength [39], wherein an excess amount of C-S-H was formed during geopolymerization [40–42].”
Effects of activator characteristics on the reaction product formation in slag binders activated using alkali silicate powder and NaOH (2012, background): “Among the precursor materials used, fly ash and ground granulated blast furnace slag have been the prominent ones because of their favorable chemistry (higher amounts of reactive silica and/or alumina species [1–6]) and abundant availability in many parts of the world.”
Isothermal reaction kinetics and temperature dependence of alkali activation of slag, fly ash and their blends (2013, methodology): “The curing temperature has been found to be less significant when compared to the effects of activator concentration and type for slag mixtures [23,24].”
Insights into material design, extrusion rheology, and properties of 3D-printable alkali-activated fly ash-based binders (2019, background): “The compressive strength results of 3D printed binders shown here suggest that the trends are similar to the compressive strengths of binders cast in a conventional manner [38,68].”
