Evolution of binder structure in sodium silicate-activated slag-metakaolin blends (2011, result): “The observed phases are in accordance with those reported by other studies [4,6,44–49] when slag is activated with sodium silicate solutions, except that gismondine is only rarely observed [23,50].”
Influence of slag chemistry on the hydration of alkali-activated blast-furnace slag — Part I: Effect of MgO (2011, methodology): “It has been observed, however, that the hydration products formeduponWGactivation incorporate much more water than the NaOH activated slags [10,28,30], which makes the comparison between the two activators difficult.”
Lightweight concretes of activated metakaolin-fly ash binders, with blast furnace slag aggregates (2010, background): “Second, it is known that BFS react with alkaline solutions [21,44] forming binding products, thus BFS grains surely reacted forming reaction products that intermixed with those of the geopolymer, forming a strong interfacial bond between the sand particles and the matrix of cementitious products.”
MgO content of slag controls phase evolution and structural changes induced by accelerated carbonation in alkali-activated binders (2014, unknown): “In general, the reaction products of the alkali-activated pastes based on COL-GBFS, AUS-GBFS and SPGBFS have average Ca/Si ratios consistent with previously reported values for similar systems [11,30,44,45].”
Strength and drying shrinkage of reactive MgO modified alkali-activated slag paste (2014, unknown): “In addition, hydrotalcite-like phases have been reported to form in many studies [32,67,68].”
Alkali-activated slag cements produced with a blended sodium carbonate/sodium silicate activator (2016, background): “These phases have been reported as the main reaction products in sodium-hydroxideand sodium-silicate-activated slag binders (Ben Haha et al., 2011; Bernal et al., 2013; Escalante-García et al., 2003).”
Effects of slag substitution on physical and mechanical properties of fly ash-based alkali activated binders (AABs) (2019, background): “2 for neat alkali-activated slag systems [7, 39, 49].”
Hydration and properties of sodium sulfate activated slag (2013, unknown): “hydration products, the microstructure and activators [18-24].”
Encapsulation of expansive powder minerals within a concentric glass capsule system for self-healing concrete (2016, result): “5 and 39 ) agree with similar observations reported in the literature [34,35], although other stronger intensity of crystalline phases causes their peaks less strong in comparison to others such as SiO2, calcite etc.”
