In pottery processes, the incorporation of sludge into the production of ceramics is something that is currently being studied, since this can be constituted as a solution environmentally for these. During the present investigation the mechanical physical characteristics of ceramic bricks with additions of residual sludge from wastewater treatment plants (PTRAR) were evaluated, determining their use as construction materials, doing this at different times; Collection and characterization; Selection of percentages of additions and temperatures and Determination of physical and mechanical characteristics according to NTC-4017. Similar compounds are found among the raw materials, clays, dry and calcined sludge (SiO 2) 59; 56 and 57%, (Al2O3) 19; 11 and 12%, and (Fe 2 O 3) 4; 6 and 7%. The characteristics of the bricks showed higher strength (29.8 MPa) and lower absorptions (15.53 and 19.49%) for bricks cooked at temperatures of 1000 °C. Seeing better results at this temperature.
