摘要

Geopolymers, known for their sustainable and high-performance properties, this research investigates the synthesis and optimization of geopolymers, emphasizing their potential as sustainable and efficient construction materials. The study evaluates the effects of raw material selection, activator concentration, curing conditions, particle size distribution, and post-curing treatments on geopolymerization. The research emphasizes the transformation from fly ash to geopolymer, focusing on the resulting changes in crystalline and amorphous phases. In parallel, the study thoroughly investigates material properties through comprehensive characterization methods. Fourier transform infrared spectroscopy analyzes chemical bonds and functional groups. Scanning electron microscopy coupled with energy-dispersive spectroscopy reveals detailed microstructural and compositional features. Thermal analyses, including thermogravimetric analysis, and differential scanning calorimetry, evaluate thermal stability and behavior. Integrating box-Behnken design and detailed characterization techniques contributes to a deeper understanding of the geopolymerization process. The results presented here have implications for advancing sustainable construction materials and promoting innovation in the geopolymer technology field. The findings offer valuable contributions to the understanding and design of geopolymers with enhanced properties, promoting sustainable advancements in construction material technologies.
