Synthetic aluminosilicate based geopolymers – Second generation geopolymer HPLC stationary phases
Analytica Chimica Acta, 2019A survey of existing stationary phases classified by the United States Pharmacopeia reveals that 120 groups of chromatographic supports mostly utilize silica-silane chemistry, polymeric materials along with some niche metal oxides. In this work, the synthesis and characterization of transition-metal free geopolymers as a new class of stationary phases ...

Thermal Properties of Geopolymers
2009The thermal properties of metakaolin and fly ash geopolymers with comparisons to ordinary Portland cement (OPC) are reviewed. The role and presence of secondary phases and aggregates are also discussed. The chapter explores the following characteristics of geopolymers upon exposure to high temperature: thermal expansion, weight loss, thermodynamics ...

Geopolymer depolymerization index
Vibrational Spectroscopy, 2016Glass-like behavior of the geopolymer samples have been investigated by determination of the influence of the geopolymerization reaction equilibrium on the types of SiO4 tetrahedra polymerization present. In order to manipulate geopolymerization reaction equilibrium, aluminum and sodium content in the samples was varied.
