The wood industrialization generates residues big quantity, that are thrown in the environment, and they aren't profited in your totality, or when at most are used to energy generation causing also environmental pollution. This research had as objective to evaluate by means of physical, interface fiber-head office mechanical rehearsals and analysis, for sweeping electronic microscopy, the lumber industry residues utilization for cement-wood particleboard molding. They were going evaluated the compatibility of six dicotyledonous species native of Amazonian, and their mixture in equal parts, with compression axial rehearsals in cylindrical bodies-of-proof, for choice of that better performance for application in cement-wood particleboard. The residues were going used to the natural and submitted to the treatment wash in hot water for two hours, for influence verification of this treatment. The used cement was CP V ARI, with the relation cement/wood 3: 1 on mass, together with the additive accelerators of catches aluminum sulfate to 3% and calcium chloride to 3% and 5%. The results of compression axial rehearsal indicated three species with potential for use in plates, with the treatment wash agreement with the accelerator of catches calcium chloride to 5%. The species Cedrela odorata L. (Cedar), exhibited the best performance in the physical and mechanical rehearsals, overcoming plates manufacturers specifications, being, potentially the residue more indicated for utilization in cement-wood particleboard.
