Physical and mechanical properties of Thai bansh (Thyrsostachys siamensis has been studied at three different height positions along the culm. These properties were found to vary significantly along the culm height. The moisture content, sluinkage and the bending strength decreased as the height mcreased, but the specific gravity, compressive strength and modulus of elasticity increased with the height. Variations of these properties were also found significant among the species.
The physical and mechanical properties of Jhau (Caswarma equisetifolia) grown in Chattogram
timber species were studied. The results indicate that jhau wood is fallen in very heavy and very
strong categories. The specific gravity and the volumetric shrinkage of Jhau timber is higher than
that of Chattogram teak which was recommended as standard for comparison of other timber
species in Bangladesh. The species can be used for house posts, agricultural implements, tool
handles and other household articles.
The strength and seasoning properties of timber species, Swietenia macrophylla King were studied. 5.
macrophylla is found moderately strong. The volumetric shrinkage is higher and the specific gravity is
lower than that of Chittagong teak which was recommended as standard for comparison of other timber
species of Bangladesh. The species can be seasoned properly in the solar kiln and in air-drying yard. The
species is found suitable for making furniture and other household articles as far as Seasoning and strength
properties are concerned
