Fabrication of Geopolymer Tile from Waste Ceramic Lunchbox Container

Ceramic pots are used as one of the lunchbox containers; however, most of them are discarded after a single use. In this study, a method was investigated to produce tile-shaped hardened materials with sufficient strength for use as interior materials by utilizing the geopolymerization reaction with waste ceramic pots as a raw material. The hardened materials were characterized using various analytical instruments, and their mechanical properties were assessed through three-point bending tests. The bending strength satisfied the requirements for indoor tiles specified in the JIS A5209 standard, reaching a maximum value of 48.3 N/mm2.
