摘要：The production of enormous quantities o f sewage sludge is a compulsory result of wastewater treatment. This sludge is massive and can contain toxic substances; consequently, it needs to be valorized suitably. However, an appropriate treatment can lead to a successful reuse of this sludge in cement manufacturing. This investigatio n studies the impact of a thermal treatment on sewage sludge, for its reuse in cement, and presents the results of the characterization of calcined slud ges, at different temperatures, by Atomic Emission Spectroscopy Inductively Coupled Plasma, X-ray Diffraction and Fourier Transform Infrared analysis. The results show that the calcined sludges contain oxides of different sizes, quartz, calcite, dolomite and lime; and several metals Ca, Mn, Mg, Na, P, Fe and Si. The compositions of calcined sludges recommend their use in cement manufacturing.
