Assessment of the impact on boron treatment for finger-jointed Pine (Pinus caribaea) wood by impregnation method

Timber material could be considered as a leading environmental friendly construction material. Timber stores as much as 15 times CO 2 released during its manufacture whereas Aluminium and steel store negligible amounts. Finger joint is a sustainable, eco-friendly and economically valuable concept for timber industry. It ensures the sustainable utilization of small wood cut pieces which removed as waste. Chemical protection of wood is performed with preservatives, such as fungicides, insecticides, fire retardants and UV protective finishes that are applied for wood materials. Softwood timber species are subjected to easily deteriorate by the actions of wood destroying agents. Thus preservation is needed to enhance the durability of such wood. Major objective of this study is to evaluate of the impact on Boron treatment for finger-jointed Pine wood specimens and enhanced the durability of Pine wood timber planks. Specimens with 19 mm finger joint length of Pine wood were used for this study. Average tensile strength values of treated and untreated finger-jointed Pine specimens are higher than the recommended minimum requirement of tensile strength value ( ≥ 10 N/mm 2 ). Failure modes of treated and untreated finger-jointed Pine specimens also described. Thus, it can be recommended that Boron treated finger-jointed Pine timber planks with 19 mm long fingers can be effectively used in industrial applications with enhancing the durability of Pine wood timber planks.
