RESUMO:

The civil construction sector in Brazil seeks to expand and apply techniques to construction materials that minimize environmental impact. In this context, wood stands out for being a renewable and versatile material, which encompasses several construction systems and engineered products. LVL (Laminated Veneer Lumber) is an engineered product made of thin layers of wood veneers with a thickness varying between 2 to 3 mm, glued with synthetic adhesive with the fibers arranged parallel to the main axis of the element. The Eucalyptus genus has enormous potential in terms of supplying wood for the most varied purposes and, in addition, its wood is booming in the civil construction sector, but it is necessary that its wood be fully treated for use in structural elements. This work aims to characterize the strength classes and compare the physical and mechanical properties of the structural elements in LVL of the species Eucalyptus pellita with treated and untreated CCA veneers. The methodology is organized in two parts: in the first, the lamination, cooking and drying and preservation processes are described, and in the second, the physical tests of moisture and density, the mechanical shear tests parallel to the fibers, compression parallel to the fibers and flexion are presented. simple for solid wood and also for LVL pieces, according to NBR 7190 (ABNT, 1997). The results showed that LVL made with Eucalyptus pellita veneers is an engineered product with good mechanical performance and has great potential to be used in civil construction, as this product has several barriers against termites in its composition the environmental impact.
