摘要：

This paper studies the technological feasibility of using iron ore tailings as additives in cement pavers for the optimization of the mechanical properties and color modulation.Thus, to study the physical, chemical, optical and morphological properties of the tailings, they were characterized for the composition, mineralogy and granulometry. To optimize the procedure of preparing iron ore tailings as additives in the production of new concrete pavers and to determine their effects on the properties of pavers they, were added in ratios of 0% to 50% in substitution of traditional aggregates. The pavers were characterized for hermeticity and mechanical properties.
