Municipal solid waste incineration(MSWI) bottom ash consists of glassy materials, ceramics, ferrous materials mainly. Therefore, in some European countries, it is used as construction material. But, the bottom ash is more considered as a chemically reactive material that releases hazardous heavy metals. In order to manage the bottom ash, understanding of the carbonation process is necessary. Because their influence on carbonation reaction in bottom ash may has a significant effect on the leaching characteristics of contaminants such as heavy metals. To gain a proper appreciation of the carbonation role of mineral constituent in bottom ash, it is essential to understand the relationships between their morphology, composition and their influence on carbonation reaction. Therefore, we carried out the study on mineral constituent of bottom ash and their influence on carbonation reaction.
