Influence of the Addition of Waste Glass and Microbiological Performance of Metakaolin?Based Geopolymers Cement

Glass recycling reduces the amount of waste to be treated or disposed in landfills, allowing both limit environmental damage and save on costs transportation disposal waste. In this paper, an advantageous method for glass containers (bottles, jars, jars food, glasses, cans drinks, etc.) is presented. The crushed without being washed separated from any foreign bodies it safely incorporated into a metakaolin (MK)-based geopolymeric matrix. Pure MK mixtures obtained by adding different percentages (30–50 wt%) cullet are consolidated via alkali activation at 50°C. Infrared spectroscopy able reveal formation bonds between matrix glass. Leaching tests carried out evaluate eventual release toxic metals, while antibacterial complete evaluation final products that show how mechanical performance modified cullet.
