Application of Iron Ore Tailings From The Dam Collapse In Mariana - MG In The Development of New Construction Materials: A Systematic Review

Objective: The study evaluates, through a systematic review, the possible applications of Iron Ore Tailings (IOT) from the collapse of the Fundão Dam in Mariana - MG in the production of new construction materials.   Theoretical Framework: Based on concepts of systematic reviews, without analytical bias, and theories of recycling industrial waste and sustainable materials.   Method: An adaptation of the Systematic Search Flow method was used, analyzing the waste preparation, characterization methods, mineral composition, materials produced and tests carried out from the selected articles.   Results and Discussion: Most cases required prior IOT preparation. For characterization, the most used methods were X-ray Diffraction, Granulometric Analysis and Scanning Electron Microscopy. The IOT consisted mainly of quartz and hematite. Materials produced included concrete, mortar, blocks and bricks, plastic and ceramic composites, which were evaluated by water absorption and compressive strength tests.   Research Implications: Provides insights into the application of the paper's results in the management of mining tailings and the production of sustainable materials using IOT, in addition to guiding new research.   Originality/Value: The review demonstrates the feasibility of using IOT from dam collapse in the production of new construction materials and innovates by presenting graphic results, facilitating reading and understanding. The relevance is evidenced by the potential integration of results into new research, socio-environmental management strategies and sustainable development in construction.
