Iron ore tailings (IOT), Hidraulic tile, SustentabilityAbstract
In this study, four types of iron ore tailings (IOT) were evaluated as an alternative source of raw material for the manufacture of hydraulic tiles. Eight mixtures were prepared, replacing Portland cement with RMF at 25 and 50% by weight for each type of IOT. The waste presented different chemical composition, granulometry and crystalline phases. The colorimetry of the pastes with IOT in different proportions revealed different colors, enabling the production of hydraulic tiles with a sophisticated design. The compressive strength results of cements composed with IOT proved to be adequate in relation to Brazilian and international standards for cements. Formulations with 25% IOT showed the best results in compressive strength and lower mass loss when exposed to acid attack. The flexural strength results of hydraulic tiles with different IOT combinations were satisfactory. The concentration results of toxic chemical elements/parameters were lower than the limits established by standard, indicating that the use of IOT does not present risks of environmental contamination. Finally, the combination of different types of IOT in different proportions with Portland cement demonstrated synergy, generating color variations and satisfactory mechanical properties to produce sustainable hydraulic tiles.
