Abstract:
An important challenge of cement industry is the waste reuse as a feasible substitute of natural materials, thus
reducing cement manufacture footprint. A critical gap in literature is the lack of a comprehensive overview on
minor element effects commonly carried from wastes. This study aimed to fill this gap investigating the effects of
multiple minor element occurrence (Mg, S, Na and Cl) on Ordinary Portland Clinker mineralogy, microstructure,
phase polymorphism and chemical reactions occurring during clinkering. The findings highlighted that minor
elements are strongly correlated to each other in influencing clinker properties: during clinkering, all raw meals
exhibited similar reaction temperatures and melting phase formation; conversely, large differences are observed
on reactivity, crystal phase composition and polymorphism.
