    This study proposes the use of white ceramic waste (RCB), generated in the city of Manaus, as a pozzolanic material in mortar production. X-ray fluorescence and diffraction analyses identified the presence of silicon, aluminum, iron, and sodium oxides in proportions that comply with ABNT NBR 12653/1992 standards. Five mixtures with varying proportions of RCB, sand, and cement were tested and evaluated for porosity, water absorption, specific mass, and compressive strength. The results indicated that the produced mortars can be classified as Class PI and P2, according to ABNT NBR 13279, demonstrating the technical feasibility of replacing up to 50% of natural aggregate with RCB, reducing costs and environmental impact.
