Since 2003, researchers have attempted to reuse incinerator bottom ash (IBA), the residual from incinerating municipal solid waste, for ceramic production. This study focused on investigating proper IBA replacement level for manufacturing interior and exterior floor tiles. Firstly, raw materials of clay and IBA underwent SEM, EDS, and TCLP tests to determine their chemical contents. Six sets of specimens with different replacement levels of IBA (0%, 5%, 10%, 15%, 20%, and 30%) were then prepared. The specimens were calcined at 1000℃, 1050℃,1100℃, and 1150℃ and subsequently put through a series of mechanical tests to compare their performance. NMR (nuclear magnetic resonance spectroscopy) were also used to determining the organic compound structure after each specimens’ crystallization. Research results showed that proper mix of IBA up to 20% could result in quality tiles complying with specifications for interior and exterior flooring applications at certain kiln temperatures, while the specimens with 30% IBA failed to meet either bending strength or size shrinkage requirement at all kiln temperatures, and could not deliver a satisfactory result no matter what. |
