FT-IR Study, Thermal Analysis, and Evaluation of the Antibacterial Activity of a MK-Geopolymer Mortar Using Glass Waste as Fine Aggregate

Food containers made from glass are separately collected urban solid waste at 76% in most parts of Europe. The cullet finds its way to re-melting, while the debris is often disposed of. With this contribution, we suggest an upcycling process where simply ground without any washing operation and added alkali-activated paste. Metakaolin-based geopolymer mortar with coarsely as fine aggregate has been prepared via alkali activation NaOH Na-silicate. After 7, 14 28 days room temperature curing time, 3D network was investigated by Fourier-transform infrared spectroscopy (FT-IR). Vibrational spectra revealed geopolymerization occurrences, results which have supported both FT-IR deconvoluted thermogravimetric analysis (TGA). Finally, antibacterial properties were against gram-negative (E. coli) gram-positive faecalis) bacterial strains. ability cured geopolymers inhibit growth bacterium assayed.
