[PDF] Paper Mill Sludge Ash as Supplementary Cementitious

Paper mill sludge is often incinerated for heat recovering and also for an important volume reduction. In Italy about 6x10 5 tons of paper sludge is yearly produced giving 60kg of paper ash per ton. In this project, the ash coming from burning of paper mill sludge from primary mechanical separation process, fired as single fuel, was studied in order to evaluate its use as supplementary
