“…The basic and apparent density determined for the studied Indian cedar wood were 391 kg/m³ and 502 kg/ m³, respectively. In the literature it is possible to find studies on the apparent density of this wood, with the following results: 440 kg/m³ (Prado et al 2003), 500 kg/m³ (Trianoski et al 2011), 490 kg/m³ (Tello 2009), 460 kg/m³ (Trianoski 2010), and 480 g/cm³ (Suirezs et al 2015).…”

Indian cedar (Acrocarpus fraxinifolius) is a wood species that occurs naturally in India, Myanmar (Burma) and Bangladesh, and has a high commercial value, with characteristics like mahogany and native cedars. The planting of Indian cedar has been undertaken in Brazil, but there is little information available regarding the characterization of the species. Therefore, considering its timber potential and its possibility of development in the country, the present work aimed to evaluate the physical, chemical, and mechanical properties of 9-year-old Indian cedar wood, planted in the southern region of Brazil. A low specific mass (502 kg/m³), low average dimensional stability (anisotropy coefficient of 2,09 %) was observed, in addition to the low content of extractives (1,94 %). From the mechanical characterization, an average value for the elastic modulus of 8963 MPa was obtained, and for the compressive strength parallel to the grain the average and characteristic values were 32,14 MPa and 21,46 MPa, respectively. This indicates that this wood belongs to resistance class C20 (dicotyledons). The results obtained classify the wood for use in light, external, or internal civil construction
