The search for a more sustainable productive chain, in the civil construction industry, is directly related to the incorporation of recyclable materials in its products, which demands an extensive amount of studies and evaluations on their properties and their effects. Considering this, this work aimed to evaluate the red ceramic residue (RCV), from the manufacture of sealing bricks, as a partial substitute for fine aggregate or agglomerate in mortars. The application was evaluated in cement and sand mortars for physical performance, through capillary absorption tests, immersion absorption and voids index, and mechanical, by axial compression tests and flexural tensile tests. The traces were 1: 3 and 1: 6, with contents of 5% and 10% of partial substitution to the binder, and 10%, 15%, and 20% to the aggregate. In both types of mortar, they were more affected when replacing in the aggregate compared to replacing in the binder, given the porosity of the RCV. The substitutions in the binder made them behave closer to the reference traits, even at 10% levels.
