The investigation of the MSWI bottom ash fines (0-2 mm) as binder substitute after combined treatments

In this study, a series of treatments is used to upgrade the quality of the MSWI bottom ash fines (0-2 mm) from a waste-to-energy plant in the Netherlands. The efficiency of combined treatments on upgrading the quality of fine bottom ash particles to be used as cementitious material is studied. The leaching properties of treated bottom ash fines are analyzed according to the Dutch legislation. Additionally, their physical and chemical properties (density, chemical composition, hydration influence, etc.) are characterized. Finally, the hydration of the cement mixed with treated bottom ash is investigated by calorimetric measurements
