• Formation of one-part-mixing geopolymers and geopolymer ceramics from geopolymer powder (2017, neutral): “…of aluminosilicate sources in highly alkaline medium releasing Si and Al species, diffusion, exchange and oligomerization between the dissolved species in aluminosilicates and alkaline solution with formation of small coagulated structures, gelation and lastly hardening to form hard solid [9-11].”
• Fly ash-based geopolymer: clean production, properties and applications (2016, background): “In aluminosilicate monomers, Si4+ is partially substituted by Al3+, and the resultant negative charge in the aluminosilicate chains is balanced by alkali cations such as Na+ or K+ (Davidovits, 2002; Dimas et al., 2009) (Fig.”

Thermodynamics of sodium silica (2013, background): “The modulus Ms will thus play a very important role in determining the kinetics and products of geopolymerization, since the distribution of poly-silicate anions in solution can affect the precipitation of silicates to a significant extent [6].”
• Mechanical activation of fly ash: Effect on reaction, structure and properties of resulting geopolymer (2011, background): “The IR peak around 1000 cm 1 is the result of overlapping of IR peaks related to SiQ (n = 0–4) structural units [34–39].”
