摘要

本研究以偏高岭土为原料，通过煅烧国产高岭土获得偏高岭土。在15～60oC的地质聚合温度范围内，测定了四种系列碱性活化剂的热力学参数：密度、粘度、声速和折射率。通过X射线衍射（XRD）、FTIR和拉曼光谱、扫描电子显微镜（SEM）和能量分散X射线（EDX）光谱对样品进行了表征。FTIR分析的结果与拉曼光谱的结果相关。由于聚合过程，声子光谱的变化得到了证实。活化剂的不同浓度不会显著改变Si/Al比。

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 of four series of alkaline activatorswere determined over the temperature range from 15 to 60oC of process of geopolymerization. The samples were characterized by X-ray diffraction (XRD), FTIR and Raman Spectroscopy, Scanning Electron Microscopy (SEM), and Energy-Dispersive X-Ray (EDX) Spectroscopy. Results of FTIR analysis correlated with results of Raman Spectroscopy. Due to the polymerization process the changes in the phonon spectrum is confirmed. The different concentrations of activators do not change notably the Si/Al ratio.
