However, it is timely catenasformis register the high number of required tests, aspect that causes a high cost for wood characterization equipment and services. Results and Discussion Tables 2 and 3 shows the mean values coefficient of variation Cvthe lowest Min and the highest Max of the physical and mechanical properties of the Cedrelinga catenaeformis Ducke wood, respectively.

Aiming to contribute to the use of new wood species in building construction, mainly in structural purposes, as well as other applications, this study intended to determine the physical and mechanical properties of Cedrelinga catenaeformis wood specie and evaluate the possibility of estimating strength and stiffness properties investigated by density.

It demonstrate the relation between these properties and cqtenaeformis apparent density but unable to use them as an estimator of these properties due its poor adjustment. Once demonstrated this possibility, it could generate decrease in costs and in time required to properties estimation.

Materials and Design, v. Thirteen specimens were used for each test, totalizing experimental results. The best fit for the estimation of f H0 and f H90 were the geometric and linear illustrated in Figure 1. Tables 4 and 5 shows the best fits by property obtained using regression models for apparent density in the catenaefor,is of the values of strength and stiffness, respectively.

Full Characterization of Calycophyllum Multiflorum wood specie.

A picture of slab doors make with Cedroarana. Regression models for the strength catenxeformis estimation of the Cedrelinga catenaeformis Ducke by the apparent density. Besides, it must be remembered that some specific testing machines are available only in research centers. No characteristic odor though green lumber can have an unpleasant scent. Material and Methods 3. Tornillo has some of the largest pores of any commercial wood in the world.

Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models Considering the significant adjustment in Table 4 and 5, it demonstrates the representativeness of the apparent density as an estimator of strength and stiffness properties of Cedrelinga catenaeformis Ducke wood. Results and Discussion 4. Evaluating the apparent density of Cedrelinga catenaeformis 0.

Arnaldo Uliana February 6, at 7: Tornillo also has a common name in Brazil: Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models. Heartwood is light to golden brown. Conclusions The results of this study permit us to conclude: A company located in Brazil https: The use of wood also meets the requirements that the current environmental appeal of products and services provided by man [].

Journal of the Korean Wood Science and Tecnology, v. Extra sanding or very sharp tools may be necessary to obtain a smooth finish. Moreover, the use of ANOVA, which allows to accept or not the representativeness of the tested models, the coefficient of determination values R 2 were obtained as a way to evaluate the capability of the apparent density to explain the estimated dependent variable.

Coarse, uniform texture with moderate natural luster. It should be noted that 13 values for each one of its physical 3 and mechanical properties 12 were investigated, resulting in experimental values obtained.

Wood, a natural and sustainable resource, has been used by humankind for several purposes especially in construction and some manufacturing sectors. Save my catenaefornis, email, and website in this browser for catennaeformis next time I comment. Rated as moderately durable; poor insect resistance.


Rio de Janeiro, p. Density, some catenaeforrmis properties and natural durability of stem and branch wood of two tropical hardwood catenaeformls for ground applications. Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Tornillo.

Due to predatory harvest of well-known wood species and in consequence, possible shortage of these essences, it is indispensable to characterize new wood species. Physical properties results for the Cedrelinga catenaeformis Ducke wood. Prices are moderate for an imported hardwood. Besides, with the analysis of variance ANOVAtesting several regression models, it has hoped to estimate the values of strength and stiffness as a function of apparent density.

These large pores give it a unique open texture, with the pores appearing as thin dark veins on all facegrain surfaces. To use of wood rationally in a large range of possibilities, the knowledge of its anatomical, chemical, physical and mechanical properties is crucial. Anais do Congresso Florestal brasileiro 6: Mechanical properties results for the Cedrelinga catenaeformis Ducke wood.

Very large, open pores also give a pronounced veined look to facegrain surfaces. Thus, Cedrelinga catenaeformis Ducke appears as a very interesting option, especially to Brazilian Amazonian Region, the cedrelknga and southeast part of Brazilian country, cedrelings the occurrence of this wood specie is more noticeable [5].

Tropical South America Tree Size: In consequence, the prices on market were meanly affected and it got confirmed it is indispensable to define new species to replace the traditional ones used in building construction [1, 3].

Compared with Liquidambar sp.
