Although fly ash is a solid waste of coal-fired power plants, it is also a potential raw material for the building materials industry. In the present work, the fly ash collected from Mong Duong I power plant was characterized and used as a substitute for kaolin and feldspar at sixteen percent of a ceramic tile raw mix. The results show that fly ash promotes sintering and helps upgrade wall tiles from unsatisfactory to grade BIIa and floor tiles from grade BIII to grade BIb. These changes have significant economic and environmental implications. However, due to a relatively high firing shrinkage, it is necessary to have appropriate adjustments if applied in industrial production.
