ABSTRACT
Evaluation of various wood species for their physico-mechanical properties and further recommendations for rationale utilization of studied wood species on the bases of strength (physico-mechanical) properties was accomplished in this research study. ASTM international standards of wood testing were followed for physico-mechanical tests, i.e. Density, MoR, MoE, cleavage, tensile, compression parallel to grains, compression perpendicular to grains, End hardness and Side hardness. Results revealed that Papular deltiodes has low-very low strength wood species with moderate hardness; Papular euphratica were a high-density species having high elasticity, low bending and compression, with medium hardness; Eucalyptus citridora was hard with medium to very high strength properties, Eucalyptus camaldulensis was high in both density and compression strength, low and very low in bending and elasticity respectively having medium hardness. Paulownia catalpifolia and Paulownia fortunei both were low in strength. Furthermore, Eucalyptus citridora was the highest density among the studied wood species. Eucalyptus citridora wood was in the highest strength as per results. It may be used for furniture, bearing blocks, bowls, beams, columns, posts & struts, flooring, paving blocks, rollers, sleepers, wedges, wheelwrights work, and bolted timbers joints, nailed timbers, notched timber, mallets and others. Eucalyptus camaldulensis may be used in bearing blocks, bolted timbers, carving, furniture, patterns, pencil, paving blocks, rollers, sheaves, shuttles, wedges, etc. Popular euphratica may be used for bearing blocks, bolted timber, carving, columns and poles, posts, furniture, mallets, nailed timber, panelling, wedges and others. Papular deltoides may be used for bowls, carving, mallets, panelling, patterns, pencil, shuttles, toys work, matchsticks etc. Paulownia catalpifolia and Paulownia fortunei have very low strength and may be used in toys, matchsticks, articles and woodworking, where low strength properties are required.
