• Impact of Alkali Silica Reaction on Fly Ash-Based Geopolymer Concrete (2013, background): “The GPC specimens exhibited strong peaks at 960 cm−1, which can be related to the Si-O-Al bond of the newly formed geopolymer gel (Hajimohammadi et al. 2011; GarciaLodeiro et al. 2009; Garcia-Lodeiro et al. 2010).”
• Solid-state nuclear magnetic resonance spectroscopy of cements (2019, background): “enced by kinetic limitations on silica and alumina release from solid precursors if these are used [253,254] and consequently evolves over time as the reaction process proceeds [237].”
• Effects of slag substitution on physical and mechanical properties of fly ash-based alkali activated binders (AABs) (2019, background): “Higher Si availability resulted in higher compressive strength and this has been associated with a more thorough dissolution of Al [24].”

• Toward an indexing approach to evaluate fly ashes for geopolymer manufacture (2016, background): “In previous studies [46], it has been found that key factors affecting the compressive strength development of fly ash -based geopolymers include pa rticle size distribution, the content of glassy phases and the content of glass network modifying species (mainly alkali and alkali earth metals).”
