Abstract
This paper describes the approach and objectives of the research project as well as the results obtained in the initial phases. The starting waste used for this research is a Spanish paper sludge coming from a paper industry which uses 100% of recycled paper as raw material. The first results show that the calcining temperature and stay in furnace play an important role on the pozzolanic activity of the calcined product and in its reaction kinetics. Calcining temperatures of 700°C and 2 hours of stay were the fixed conditions in order to get the best pozzolanic properties for this calcined sludge.
