The influence of thermodynamic parameters on alkaline activator of geopolymers and structure of geopolymers [PDF]
Macedonian Journal of Chemistry and Chemical Engineering, 2021 Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 °C for the process of geopolymerization. Mixtures of Na2SiO3and NaOH of different molar concentrations (from 2M to 8M with step 2) were used as an alkaline activator.
