- The Study′s Chemical Interaction of the Sodium Silicate Solution with Extender Pigments to Investigate High Heat Resistance Silicate Coating.: This research focuses on the geopolymerization process between sodium silicate solution and extender pigments (ZnO, TiO2, Fe2O3, CaCO3, and Na2SiF6). The study utilizes Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), and X-ray diffraction (XRD) to analyze the chemical interactions. Findings indicate enhanced thermal stability of the coatings, making them suitable for high-temperature applications (Le et al., 2021).
- Preparation and properties of metakaolin-fumed-silica geopolymer modified with sodium silicate and potassium silicate activators.: This paper explores the effects of sodium silicate and potassium silicate activators on the properties of metakaolin-fumed-silica geopolymers. It provides insights into the structural and mechanical properties through a combination of experimental techniques, demonstrating improvements in material performance for construction applications (Jin et al., 2024).
- Unravelling the stability of solvated silicate species in sodium silicate activator solution of different silica modulus by FTIR and NMR studies and their chemical reactivity on metakaolin and fly ash geopolymerisation.: This study investigates the stability and reactivity of solvated silicate species in sodium silicate solutions with varying silica modulus. Using FTIR and NMR spectroscopy, it elucidates the mechanisms of geopolymerisation with metakaolin and fly ash, highlighting the formation of stable geopolymer structures suitable for sustainable construction materials (Sharmila et al., 2024).
