The incorporation of residues in cement matrices is a viable alternative for obtaining new products for civil construction and a sustainable solution for the disposal of materials discarded by industries. In this context, the objective of the study was to evaluate the potential use of quartzite and particles of Hevea brasiliensis in the production of cement-wood panels. Quartzite residues and Hevea brasiliensis wood particles were obtained and characterized. The panels were produced with CPV-ARI Portland cement, 4% calcium chloride (CaCl2) in relation to cement mass, treated wood particles, and replacing cement with quartzite in different proportions (0, 10, 20, and 40%), totaling four treatments. The physical-mechanical and microstructural properties of the panels were determined. Replacing cement with 10 and 20% quartzite contributed to the improvement in water absorption and thickness swelling, and due to increased density, MOE and MOR also increased with 20% quartzite. The cement-wood panels were suitable for non-structural and internal use, requiring further studies to evaluate alternative methods of replacing these residues.
