With the exponential increase in industrial and urban solid waste generation coupled with the lack of environmentally sound disposal alternatives coupled with an industry with high potential to absorb this waste in large quantities without altering or improving product quality, as is the case with industry. of red ceramic, motivated this work. Therefore, the incorporation of blast furnace slag, a steel waste, into a clay matrix for the manufacture of red ceramic was studied. The raw materials were characterized chemically (XRF and EDS), mineralogically (XRD), thermally (TG/DTG) and morphologically (SEM), and were later formed and compositions with 5, 10 and 15% of slag incorporated into the matrix. After formulation, the specimens were made and dried at room temperature and oven and then burned at 850, 950 and 1050 ° C. To determine the technological properties, the tests of water absorption, apparent porosity, bulk density and bending stress were performed. In addition, the burnt parts were characterized by XRD and SEM. The results showed that blast furnace slag retains the properties of ceramics without the waste, always reaching values within standards.
