Sulfuric acid resistance of blended ash geopolymer concrete (2013, background): “A sodalite and natrolite were also identified which were the reaction products of geopolymerisation and represent the zeolite precursor of BAG concrete [20,26,27].”
The effects of ground granulated blast-furnace slag blending with fly ash and activator content on the workability and strength properties of geopolymer concrete cured at ambient temperature (2014, methodology): “However, the strength gain occurs at a much slower rate with age due to alkaline saturation and product densification [15].”
Microstructure, strength, and moisture stability of alkali activated glass powder-based binders (2014, background): “For instance, activated fly ash binders require mild to moderate thermal curing in order to facilitate hardening and the formation of the alkali aluminosilicate binder [4,7,11] whereas activated slag binders harden and develop strength under moist curing [10,12].”
Binding mechanism and properties of alkali-activated fly ash/slag mortars (2013, background): “Xie and Xi [28] investigated the hardening mechanisms of an alkaline-activated class F fly ash and concluded that the strength of the paste increased with the decrease of the modulus of water–glass from 1.”
Alkali-activated binders: A review: Part 1. Historical background, terminology, reaction mechanisms and hydration products (2008, background): “Xie and Xi [58] studied the alkali activation of fly ashes with NaOH mixed with waterglass, and noticed that, for the SEM analysis, a large amount of crystals was detected due to unreacted waterglass which had crystallized.”
Effects of slag substitution on physical and mechanical properties of fly ash-based alkali activated binders (AABs) (2019, result): “Similar ranges have been reported in the literature [21-23].”
