Fire Resistance Behaviour of Geopolymer Concrete: An Overview (2021, background): “In the event of geopolymers based on metakaolin, thermal shrinkage, as well as phase stability with high ceiling temperatures are affected in the choice of the alkaline cation either Na, K or a combination of both for geopolymer mixture [33,35].”
Performance of refractory aluminosilicate particle/fiber-reinforced geopolymer composites (2012, background): “Reductions in the compressive strength of unreinforced MKgeopolymer at elevated temperatures are associated with the structural changes which take place as a consequence of the increased surface energy of the gel as water is released from its surface and small pores, causing the porous gel network t”
Mechanical properties of sodium and potassium activated metakaolin-based geopolymers (2012, methodology): “FTIR can be used to identify functional chemical groups within the GP matrix [20, 57-59] through analysis of the absorption and transmission speactra of molecular structures in mid-infrared frequency range (400 to 4000 cm).”
Production of nepheline/quartz ceramics from geopolymer mortars (2013, background): “Previous work on the effect of high temperatures on geopolymers has examined phase changes using XRD and NMR [15-20].”
