Influences of different drying climates on Eucalyptus camaldulensis wood properties

Abstract

One of the most important disadvantages of the wood material, whose usage is becoming more and more widespread, is the dimensional instability that occurs in its interaction with water. Therefore, studies to improve these drawbacks of wood, remain always up to date. For the mentioned purpose in this study, some chemical, morphological, physical and mechanical properties of Eucalyptus camaldulensis woods, which were naturally dried in outdoor and indoor climate in Eastern Mediterranean (Kahramanmaraş province) atmosphere conditions of Turkey, were investigated. According to the results of the study, chemical properties of Eucalyptus woods dried indoor were measured as merely 0,23 % higher than dried ones outdoor. The results of morphological measurements indicated that the fiber dimensions of eucalypt wood dried in indoor were average 1,48 % lower than the ones dried out outdoor. Also, as a result of statistical analysis, it was found that there were significant differences (ρ < 0,000) between the physical properties of Eucalyptus wood samples indoor and outdoor according to the t-test. At the same time, as a result of the t-test applied to determine the effect of drying conditions on mechanical properties of Eucalyptus wood, modulus of elasticity, compression, tensile, dynamic bending and shear strength did not cause any significant difference between indoor and outdoor, while bending and Janka hardness strengths showed significant differences at ρ < 0,000 level. Finally, when the data obtained as a whole is considered, it can be said that testing of Eucalyptus wood which requires a very sensitive drying in different climates has important contributions on the subject. Regarding eucalypts, which has a high distribution area (20 million hectares) in the world, it is recommended to relevant institutions and organizations to expand and maintain such study in the future. Lastly, according to obtained data from this study, it can be said that the experiments of Eucalyptus woods which require a very delicate drying in different environments provide important contributions on the subject.

Anatomical, physical and mechanical characterization of the wood of three eucalyptus species: E. camaldulensis Dehn, E. cladocalyx and E. gomphocephala

“…Most of these species, their fibers occupy more than 60% of wood volume, are short with about 1 mm in length and have variable cell wall thickness (Wilkes 1988). In addition, the wood fibers of 50-months-old E. camaldulensis grown in an experimental site in Portugal and mature wood of E. camaldulensis grown in Turkey are short, with 0.67 mm and 0.81 mm in length, respectively (Pirralho et al 2014;Kiliç et al 2021).…”
