This paper is a contribution to the process and usage development of bamboo as a raw material as a sustainable practice in several Brazilian economic fields, with emphasis on civil construction. The processed bamboo is used in the manufacture of glued laminates, designated as BLC, Bamboo Laminate Glued, is the object of object study. BLC beams were made using the plants Phyllostachys pubescens and Dendrocalamus giganteus, and with the usage of the Polyurethane Bicomponent and Monocomponent adhesives. Standardized specimens were prepared for the physical and mechanical characterization with obtained results compatible with other species mentioned in literature. Bamboo blades were then produced for the manufacture of BLC beams. The beams produced were submitted to the control of the glue quality (glue line resistance, and delamination) and to the static bending test in order to evaluate the rupture modes and to compare the experimental rigidity with the theoretical model. The results of the glue quality test ranged between 25.59 to 55% at the delamination test, and the results figured between 4.66 and 6.69% at the glue line resistance test. The rigidity was compared following standard ABNT NBR 7190: 2013 expression. The differences between the experimental and theoretical rigidity in BLC produced with bamboo P. pubescens and Polyurethane Bicomponent and Monocomponent adhesives were around 20.41 and 5.00%, respectively. In the BLC beams produce with D. giganteus bamboo this difference between rigidities was around 11% for both types of adhesives.
