Abstract	The three key molar ratios influencing the synthesis of potassium type poly-sialate-siloxo (K-PSS) geopolymer: n(SiO)/n(AlO), n(KO)/n(AlO), and n (HO)/n(KO) are systematically investigated in accordance with orthogonal design principle. Based on compressive strength and infrared spectra, the effects of the three molar ratios are analyzed quantitatively on the macro-and micro-scales, finally obtaining the optimum mixture proportion. Additionally, X-ray diffraction, infrared spectra and nuclear magnetic resonance with magic angle spinning measurements show that infrared spectrum peak at 1086 cm caused by the stretching vibration of [SiO] tetrahedra shifted to lower wavenumber around 1033 cm, and the 6-fold Al was transformed into 4-fold coordination during the synthesis of geopolymer. The Al exists in the form of 4-fold coordination and connects with SiO tetrahedra, finally forming amorphous geopolymeric products with framework configuration. Correspondingly the Si exists in the form of SiQ(4Al) and SiQ(2Al) units. No oligomers such isolated or small group building blocks are found.
