Bamboo has been in the focus of attention as a re-discovery of an old and available material to solve environmental problems in the construction industry. The use of full-culm bamboo in the built environment, however, depends on proper quality control/assurance of its mechanical and physical properties. In this work, a quality assessment in terms of treatment control and mechanical properties of a small production of Phyllostachys edulis bamboo poles treated with disodium octaborate tetrahydrate (DOT) was performed. A comparison between two commercial preservatives used for exterior and interior applications, chromated copper borate (CCB) and DOT respectively, in terms of the effect on the mechanical properties and treatability behaviour was also investigated. Penetration and retention analyses showed satisfactory results for the samples treated with CCB, with retention of 7.2 kg/m³, while lower …
