The influence of thermodynamic parameters on alkaline activator of geopolymers and structure of geopolymers [PDF]
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.
