The influence of thermodynamic parameters on alkaline activator of geopolymers and structure of geopolymers

In this research, the starting precursor material is metakaolin, which was obtained by calcining domestic kaolinite clay. Thermodynamic parameters: densities, viscosities, speed of sound and refractive index four series alkaline activatorswere determined over temperature range from 15 to 60oC process geopolymerization. The samples were characterized X-ray diffraction (XRD), FTIR Raman Spectroscopy, Scanning Electron Microscopy (SEM), Energy-Dispersive X-Ray (EDX) Spectroscopy. Results analysis correlated with results Due polymerization changes in phonon spectrum confirmed. different concentrations activators do not change notably Si/Al ratio.
