Abstract


The effective re-use of industrial by-products calls for an understanding of their chemical, mineralogical and physical characteristics. The by-product used in this study was coated paper industry sludge from a plant whose sole prime material is recycled paper. Due to its high organic and calcium carbonate content and the presence of several clayey materials such as talc and kaolinite, incineration conditions had a significant effect on the mineralogy of such sludge. The present study examined the impact of such conditions on the pozzolanic properties of coated paper sludge. Several temperature intervals ranging from 600 to 750 ºC were studied to determine the conditions yielding the most promising pozzolanic properties.
