The incorporation of waste generated by the steel industry in cementitious components can contribute regionally, in a sustainable way, to a significant reduction in environmental liabilities. This study aimed to analyze the physical and mechanical characteristics of concrete blocks without structural function manufactured with BSSF steel slag as a replacement for natural aggregates. Partial substitutions of 20, 40, 60, 80% of the natural aggregates were made by artificial ones in the production of the blocks. In addition to the BSSF steel slag, Portland cement, natural sand, gravel, stone powder, additive and water were used in the manufacture of blocks. The concrete blocks were manufactured in a cement industry and the entire manufacturing process was detailed. Then, the blocks were tested for dimensional analysis, water absorption, liquid area and resistance to compression at 28 and 371 days of age. With the durability study, the viability of incorporating BSSF steel slag into concrete blocks was proven, since the blocks produced met the normative requirements and still had an increase in quality.
