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. Arnaldo Uliana February 6, at 7: These large pores give it a unique open texture, with the pores appearing as thin dark veins on all facegrain surfaces.
No characteristic odor though green lumber can have an unpleasant scent. Results and Discussion 4.
Evaluating the apparent density of Cedrelinga catenaeformis 0. Leave this field empty.
Tornillo | The Wood Database – Lumber Identification (Hardwood)
A company located in Brazil https: Prices are moderate for an imported hardwood. To use of wood rationally in a large catenaeformus of possibilities, the knowledge of its anatomical, chemical, physical and mechanical properties is crucial. The mechanical properties of Cedrelinga catenaeformis obtained demonstrated compatible performance with regular wood species used in temporary civil construction.
Introduction Wood is an important and sustainable material employed in several sectors and industries of different segments nowadays and it has been used to quench humankind demands, like store food, construction of shelters and agricultural tools. Wood, a natural and sustainable resource, has been used by humankind for several purposes especially in construction and some manufacturing sectors.
Tables 4 and 5 shows the best fits by property obtained using regression models for apparent density in the estimation of the values of strength and stiffness, respectively. Projeto de estruturas de madeira. The use of wood also meets the requirements that the cedrelings environmental appeal of products and services provided by man .
All stiffness properties met the values of the coefficients of variation required by the standard and all strength properties exceed the limit but hardness cedrelinta to the grain fH90 which attended the limit, showing a Cv equal to 0.
Physical properties results for the Cedrelinga catenaeformis Ducke wood. Full Characterization of Calycophyllum Multiflorum wood specie.
Tornillo has some of the largest pores of any commercial wood in the world. Save my name, email, and website in this browser for the next time I comment. Best fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models.
Design and analysis in experiments. However, it is timely to register the high number of required tests, aspect that causes a high cost for wood characterization equipment and services. Considering that density is a fundamental property, vedrelinga values can endorse determining an appropriate estimate of some wood properties [1, 2, 7, 8, 9].

Regression models for the stiffness values estimation of the Cedrelinga catenaeformis Ducke by the apparent density. The estimation of strength and stiffness properties by density via mathematical methods regression methods could enable the engineers a better pre-design of the structure.
Variation of wood density and mechanical properties of blackwood Acacia menaloxylon R. Material and Methods 3. Considering the high-level demand and few options of well-known wood species for structural construction and manufacture purposes, predatory catenaefotmis selective harvesting has reduced market receptivity for new species whose characteristics and properties catenaefornis not yet known.
Very large, open pores also give a pronounced veined look to facegrain surfaces. Tropical South America Tree Size: 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. Density, some anatomical properties cedrelingw natural durability of stem and branch wood of two tropical hardwood species for ground applications. Rio de Janeiro, p.
