| Abstract | Eucalyptus is one of the most popular commercial woods in Thailand. It is an important raw material for various wood industries. Utilization in the form of sawn timber is limited, due to lack of basic information, given that Eucalyptus clone K7 is widely planted since it grows fast. The research objective of this study was to determine the physical and mechanical properties of Eucalyptus clone K7 as basic data for utilization in the form of sawn timber. The physical properties of K7, i.e., average specific gravity under oven dry condition was 0.52, fiber saturation point averaged between 26 to 28 percent, maximum shrinkage in tangential, radial, and longitudinal direction was 11.00, 7.00 and 0.65 percent, respectively per moisture content decrease from fiber saturation point to 0 percent and desorption isotherm. The mechanical properties, i.e., modulus of rupture was 72.45 MPa, modulus of elasticity was 6,654 MPa, compression parallel to grain was 41.94 MPa, compression perpendicular to grain was 5.33 MPa, hardness was 3,075 N, cleavage and nail holdings were 2.00 and 17.91 N/mm, respectively. Mechanical properties were compared with wood standard used for the structure and it was found that the clone K7 is not suitable for use in the main structure of a building. It can be used for furniture, buttress, flooring, pallet, wood chips for pulp industry, wood composites industry, firewood, and charcoal. |
