To mitigate the low environmental performance of civil construction, researchers began to study the incorporation of waste from other industries in construction materials. The aim of this research was to produce and characterize an eco-clinker from the reuse of grits residues (produced at cellulose manufacturing process), granite residues (produced during the processing of ornamental rocks) and iron ore tailings (produced during the processing of iron ore). To produce the eco-clinker, three mixtures were formulated considering the parameters of lime saturation factor (LSF), calculation of the Bogue potential, silica ratio (SR) and alumina ratio (AR). The pellets were burnt at a temperature of 1450ºC for 20 minutes and then, the mixtures were characterized. The eco-clinker produced presents large amounts of C2S-β. The mechanical properties in the early ages was out of date. At older ages the mechanical strength of the eco-clinkers can be compared with the mechanical strength of conventional cements.
