Isothermal reaction kinetics and temperature dependence of alkali activation of slag, fly ash and their blends (2013, background): “They require heat to overcome the activation energy barrier and form reaction products that impart the setting behavior [2,36].”
Fly ash-based geopolymer: clean production, properties and applications (2016, background): “Alkaline solution f a high concentration is generally beneficial for obtaining high compressive strength but there is an optimal range (de Vargas et al., 2011).”
An overview on the influence of various factors on the properties of geopolymer concrete derived from industrial by-products (2015, background): “Generally, a strong alkaline medium is necessary to increase the surface hydrolysis of the aluminosilicate particles present in the raw material while the concentration of the chemical activator has a pronounced effect on the mechanical properties of the geopolymers [26,27].”
