  • Gluing characteristics of Papua New Guinea timber species for various
           non-structural applications

    • Abstract: Abstract: Papua New Guinea (PNG) has abundant natural forest resources but there are many constraints which need to be addressed to support the development of competitive value-added wood industries. There is a need to develop knowledge and capacity in wood science and processing technologies which support successful domestic value-adding wood processing enterprises. A comprehensive testing program has been developed to assess the glue‐bond strength and performance of selected commercial PNG timber species in various climatic conditions to simulate service conditions in potential market destinations. Two criteria namely shear strength and wood failure have been used to determine if a species can meet the minimum requirements for either dry use or wet use applications. The performance of 24 different PNG commercial timber species has been assessed using a one-component cross-linking polyvinyl acetate emulsion adhesive. The bondability of the selected species has been carefully estimated considering the wood density and wood moisture content for the strength and durability in dry- and wet-use conditions. The testing results show that as the wood density as a wood property factor and moisture content as a service condition factor increase, high shear strength with high wood failure become more difficult to achieve consistently. The highest shear strength and wood failure results were achieved by softwood plantation species and low-density hardwood species. Based on the testing results, the selected species have been classified into bondability classes (bond very well, bond well, bond with difficulty, very difficult to bond).
       
  • Performance of visible and Near-infrared spectroscopy to predict the
           energetic properties of wood

    • Abstract: Abstract: Wood can be used for fuel by direct burning, or as a raw material for other fuels; however, it is necessary to evaluate the energy properties to ensure the optimal use of this material. The most relevant characteristics to be analyzed are the higher heating value, volatile material content, fixed carbon content, and ash content. Along with the traditional methods, there are also non-destructive evaluations that are optimized for speed and reliability. Among these methods, visible spectroscopy and near-infrared spectroscopy have been proven to be robust for the prediction of several wood properties. The aim of this study was to evaluate the potential of visible spectroscopy and near-infrared spectroscopy for species discrimination and prediction of higher heating value, volatile material content, fixed carbon content, and ash content for Eucalyptus saligna, Eucalyptus dunnii, and Eucalyptus benthamii woods. For this purpose, multivariate principal component analysis and partial least squares regression were applied to the collected spectra. The principal component analysis satisfactorily discriminated the three species, explaining 99% of the variance of the visible spectroscopy spectra and 73% of that of the near-infrared spectra. The estimation of energetic properties through partial least squares regression was satisfactory for both visible spectroscopy and near-infrared spectroscopies, which presented calibration R² values close to 1 and low errors for all properties studied.
       
  • Effects of thermal treatment and weathering in the resistance against
           termites of a fast-growing pine wood

    • Abstract: Abstract: Considering the limited existing literature on the combined effects of thermal treatment and weathering on the resistance of fast-growing pine wood to subterranean termites, this work deals with the resistance against subterranean termites of a thermally treated and weathered fast-growing pine wood. The pine wood was thermally treated at variable temperatures (c.a. 180 ºC, 200 ºC, and 220°C) for 2 h and then exposed to artificial weathering for three months. Chemical, hygroscopic, thermal, mechanical, colorimetric, biological, and morphological characteristics were evaluated. Compared to the untreated wood, as expected, the thermal treatments yielded wood parts with improved thermal, hygroscopic and colorimetric features. The thermal treatment also helped for retaining the thermal stability, volumetric hydrophobicity, color, and roughness of the pine wood exposed to the weathering. Previous changes ascribed to the weathering process did not affect the damages attributed to the termites attack, although that wood treated at 180 ºC presented an increased resistance against the termites deterioration.
       
  • Time-moisture superposition principle in creep behavior of white oak with
           various earlywood vessel locations

    • Abstract: Abstract: Creep behavior of wood plays a fundamental role in precision processing of wood. In this work, experimental creep tests have been conducted to determine the influence of earlywood vessel location and moisture content on creep behavior of Quercus alba (white oak). Time-moisture superposition principle was applied to predict long-term creep behavior of white oak. Results revealed that both of instantaneous and 45-min strain of specimens increased with the increasing of moisture content and decreased with increasing distance between earlywood vessel belt and load-bearing surface significantly. Additionally, the time-moisture superposition principle was found to have feasibility to predict creep behavior of white oak with various earlywood vessel locations and moisture content ranges (6 % - 18 %). We believe that the proposed investigation was beneficial for the processing precision and civil engineering applications of wood.
       
  • Biosorption of methylene blue and malachite green from single and binary
           solutions by Pinus pinaster bark

    • Abstract: Abstract: Aiming to develop a sustainable separation process reducing the water pollution, in this work Pinus pinaster (cluster pine) bark from a wood veneer industry was used for methylene blue and malachite green removal from aqueous systems. For single adsorption, the influence of time (up 8 h), adsorbent dose (2,5 - 5 - 10 g·L-1), temperature (25 ºC - 40 ºC - 60 ºC), pH (2 - 4 - 6) and particle size (0,1 mm - 0,5 mm, 0,5 mm - 1 mm and 1,6 mm - 2 mm) on adsorption was investigated. To study the initial concentration effect on binary adsorption, different concentrations (0 - 5 - 25 - 50 mg·L-1) were used at 25 ºC, natural pH and a dose of 5 g·L-1. High efficiency was obtained at pH = 4 (natural pH), dose of 5 g·L-1 and particle size of 0,5 - 1 mm. Adsorption percentages higher than 70 % were reached in less than one hour, with removal almost complete at equilibrium in single systems, without temperature influence. Methylene blue was slightly better adsorbed by bark. In binary systems, dyes exhibited competitive adsorption, decreasing their removal, especially increasing the initial concentration of the other dye. Dyes adsorption followed the pseudo-second order kinetic model, whereas the Langmuir isotherm explained adsorption equilibria in mono-component systems. High adsorption capacities (41,7 mg·g-1 for malachite green and 50,0 mg·g-1 for methylene blue) were obtained at 40 ºC and natural pH indicating that pine bark can be effectively used as biosorbent.
       
  • Some physical and mechanical properties of Laminated Veneer Lumber
           reinforced with glass fiber mesh

    • Abstract: Abstract: Structural composite lumbers are used extensively in wooden structures. There are many reasons for choosing these materials, including their light weight, easy assemble, and low cost. Various studies have been conducted to increase the load carrying capacities of these materials. Reinforcement with various natural or synthetic fibers is one method that has been studied. In this study, laminated veneer lumber was produced using poplar veneers and glass fiber mesh. One-component polyurethane glue was used in the production of the boards. The modulus of rupture, modulus of elasticity in bending, impact bending strength, and splitting strength values of the control laminated veneer lumber and laminated veneer lumber reinforced with the glass fiber mesh were investigated. In addition, some physical properties such as the densities and moisture contents of the test samples were investigated. Although the reinforcement of laminated veneer lumber using glass fiber mesh had statistically significant effects on impact bending strength, and splitting strength. The effect on the modulus of rupture and the modulus of elasticity in a static bending test was not significant. In addition, the effects of the reinforcement on the densities and moisture contents of the test samples compared the control samples were statistically significant.
       
  • Investigation of wood properties and resistance of 25-year-old Gmelina
           arborea wood selected from crown region to termite attack

    • Abstract: Abstract: Gmelina arborea is widely planted and produces many useful products. However, the upper portion of the stem might be useful for some practical applications if properly managed and harvested. In order to explore the potential of this residues, this study investigated the physical, mechanical properties, and resistance of 25-year-old Gmelina arborea (gamhar) wood from the crown region to termite attack. This is with a view to enhance the use of harvesting residues of Gmelina arborea (gamhar) such that the wood in the crown region is used as the main trunk in various applications. The following wood properties including density, modulus of elasticity, modulus of rupture, and compression strength were investigated on crown wood of 25-year-old Gmelina arborea (gamhar). This study compared with results obtained from previous studies for the bole. Test for the natural resistance of the crown wood was carried out at the timber graveyard where the samples were exposed to termites for 10 weeks to determine the weight loss. The wood samples were rated weekly according to the America Standard of Testing Material. Our results showed that there were significant differences in the density of the crown wood of the three selected 25-year-old Gmelina arborea (gamhar) stands. The results for the mechanical properties of the crown wood of the three selected 25-year-old Gmelina arborea (gamhar) trees showed that there were significant differences in the compression and modulus of rupture of the wood samples from the crown region while there was no significant difference in the modulus of elasticity among the selected stands. Visual rating results showed that termite attack ranged from moderate to heavy attack, while the weight loss was not significantly different among the sampled trees. This study has shown that the density and mechanical properties of the crown wood are comparable to those from the trunk. Hence, the crown wood can be used in application as the stem wood. Also, the study has shown that wood from crown region of Gmelina arborea (gamhar) are prone to termite attack and non-durable as the wood obtained from the stem. Therefore, there is a need to apply treatments that can improve its durability and enhance its service life.
       
  • Mechanical characterization of visually graded boards from turkish fir and
           black pine by nondestructive and destructive tests

    • Abstract: Abstract: For the mechanical characterization of Turkish fir and black pine, 400 board specimens with 22 mm× 50 mm × 420 mm were visually graded according to TS 1265 standard. Nondestructive tests were here upon performed using the stress wave method. After specimens were intentionally tested under flatwise bending to research the applicability as an alternative to tension and edgewise bending tests in European strength grading system. According to analyses of variance, the mean values of MOR and MOE differed in four groups at a p<0,05 significance level for visually graded boards. High correlations were found between MOR-MOE (R2=0,837) for fir and MOR-MOE (R2=0,776) for black pine. In addition, correlations of MOR-Knot rate for fir and black pine were respectively R2=0,669 and R2=0,660 showing the effectiveness of flatwise bending tests with the visual grading standard. For nondestructive tests, the mean values of the dynamic modulus of elasticity were very close in between fir and black pine grades while the usage of defect-free density performed better than the density of the whole specimen. Higher strength classes were found for black pine boards (Class 1= C40, Class 2= C27 and Class 3= C22) compared to fir boards (Class 1= C24, Class 2= C22 and Class 3= C18), respectively. Moreover, a simplified nonlinear material model was proposed for numerical modelling, and the results were found in good agreement in terms of the bending stiffness, strength, and deformation capacity of boards especially for class 1 and class 2 in both softwood species.
       
  • Thinning wood properties of Nothofagus alpina under three different
           silvicultural conditions

    • Abstract: Abstract: The main objective of this study was to assess the properties of Nothofagus alpina (raulí) wood from thinning that originates from two sites with intensive silviculture and one similar to a secondary growth forest, with different soil, climatic conditions and age. To achieve this, some mechanical, physical and chemical-crystalline properties were characterized; studying the differences from pith to bark and between the selected trees that were taken from the thinning of the three plantations. Among the studied plantation sites, there were statistical differences in equilibrium moisture content, density and modulus of elasticity. Furthermore, FT-IR was able to differentiate the chemical-crystalline compositions from pith to bark and between plantations, while the X-Ray diffraction showed differences in the crystallinity index. It was possible to differentiate between the sites with a more intense silvicultural intervention and the one with more variable growth conditions.
       
  • Affordable SfM photogrammetry for monitoring of tests on full scale
           elastic timber gridshell structures

    • Abstract: Resumen: Para validar modelos numéricos de resistencia de estructuras, es necesario medir su deformación bajo carga. La dificultad de dicha medición aumenta con su tamaño y su complejidad. En el presente estudio se determina la geometría de una estructura laminar reticular de gran tamaño tras una prueba de carga. La estructura fue cargada en sus cinco nodos centrales con un peso suspendido de 105 kg por nodo. Se generó el modelo 3D de la estructura sin carga y bajo carga, empleando fotogrametría usando software PhotoModeler Scanner y Metashape. El error máximo en la medida de las distancias sobre la escena fue 1,31 mm, que corresponde al 0,17 % respecto a la diagonal de la base de la estructura. El mayor error medio se dio bajo carga máxima, 0,70 mm de acuerdo a Metashapee y 0,44 mm en PhotoModeler Scanner. El perfil de la estructura bajo carga es coherente con la deformación prevista. La calidad de medida del modelo 3D resultó ser altamente uniforme. Este estudio releva el uso de fotos que han sido tomadas varios años después, a través de la fotogrametría utilizando softwares avanzados.Abstract: Numerical models of the resistance of structures must be validated through the measurement of their deformation under load, which is made difficult by size and complexity. In the present study, the geometry of a large reticular laminar structure is determined after a load test. The structure was loaded at its five central nodes with a suspended weight of 105 kg per node. The 3D model of the structure without load and under load was generated using the photogrammetric with using software PhotoModeler Scanner and Metashape. The maximum error in measuring the distances on the scene was 1,31 mm, corresponding to 0,17% concerning the diagonal of the structure's base. The largest mean error occurred under a maximum load of 0,70 mm according to all Metashapee, and 0,44 mm in PhotoModeler Scanner. The profile of the structure under load is consistent with the predicted deformation. The measurement quality of the 3D model turned out to be highly uniform. This study reveals the use of photos that have been taken several years later, through photogrammetry using advanced software.
       
  • Influence of thermal pretreatments on dimensional change and humidity
           sensitivity of densified spruce and poplar wood

    • Abstract: Abstract: Densification modification is an effective method to improve many properties of wood. However, densified wood is sensitive to humidity and is not dimensionally stable. The effect of thermal pretreatments on the dimensional change and humidity sensitivity of densified Picea orientalis (spruce) and Populus nigra (poplar) wood were investigated. A thermal pre-treatment was applied on the wood specimens at 140 °C, 160 °C, 180 °C, and 200 °C for 7 h and 9 h. Wood specimens were then compressed at ratios of 20 % and 40 % at a temperature of 150 °C. The results showed that spring-back and thickness swelling increased in all specimens (thermally pre-treated and untreated) depending on the increase in compression ratio. However, set-recovery was determined higher at 20 % compression ratio. The equilibrium moisture content values of untreated specimens and thermally pre-treated specimens at low temperatures (140 ºC and 160 ºC) were found lower than uncompressed specimens. The impact of compression ratio on equilibrium moisture content was not clear. Thermal pretreatments significantly affected the dimensional stability and hygroscopicity of densified specimens (especially poplar wood). Depending on the increase in thermal pre-treatment temperature and duration, spring-back, set-recovery and thickness swelling in wood specimens decreased up to 31 %, 67 % and 62 %, respectively. In addition, equilibrium moisture content and water absorption decreased with the increase in thermal pre-treatment temperature and duration. Moreover, the thermal treatment temperature was more important than duration on the investigated properties.
       
  • Tonkin bamboo (Pseudosasa amabilis) as a material to explore in Ecodesign.

    • Abstract: Resumen: El análisis del ciclo de vida (ACV) permite evaluar el impacto ambiental en las diferentes etapas de un diseño/producto. En el caso de la etapa de selección de materiales, entre las materias primas que tienen un mayor impacto ambiental y alto consumo energético se encuentra el acero. En este contexto, en esta investigación se estudia el uso de Pseudosasa amabilis (bambú Tonkin) como material estructural y estrategia de Ecodiseño, se compara su impacto medioambiental con el del acero en un rediseño de un puesto de mercado para frutas y verduras. Para llevar a cabo el proceso de diseño, se ha trabajado bajo el enfoque de Diseño para la Sostenibilidad (D4S) con la herramienta SolidWorks®, en la que se ha desarrollado el diseño de detalle, incluyendo el estudio del comportamiento estático y ACV, es decir, el estudio de la sostenibilidad de la estructura en el marco del nuevo paradigma de la Economía Circular. Se realizó el rediseño con bambú Tonkin, a partir de un muestreo que arrojó unos datos medios de 30 mm de diámetro y espesor de 6 mm. Los resultados obtenidos, de forma teórico-experimental y con la simulación numérica, confirman que el bambú Tonkin tanto en el análisis de elementos finitos (FEA) como en el estudio de sostenibilidad (ACV), es un material con unas excelentes cualidades estructurales a la vez que tiene un impacto medioambiental mínimo. Es por ello, que se proponen nuevas líneas de trabajo y se invita a otros grupos de investigación a que se interesen sobre este material verde desconocido.Abstract: The life cycle analysis (LCA) allows to evaluate the environmental impact in the different stages of a design/product. In the case of the material selection stage, among the raw materials that has a high environmental impact and energy consumption is the steel. In this context, this research studies the use of Pseudosasa amabilis (Tonkin bamboo) as a structural material and an Ecodesign strategy, it compares its environmental impact with that of steel in a redesign of a market stall for fruits and vegetables. To carry out the design process, the study worked under the Design for Sustainability (D4S) approach with the SolidWorks® tool, in which the detailed design has been developed, including the study of the static behavior and ACV, that is, the study of the sustainability of the structure within the framework of the new paradigm of the Circular Economy. The material selected for the redesign is a Tonkin bamboo, from a sampling that threw average data of 30 mm in diameter and thickness of 6 mm. The results obtained, theoretical-experimentally and whit the numerical simulation, confirm that the Tonkin bamboo, both in the finite element analysis (FEA) and in the sustainability study (ACV), is a material with excellent structural qualities as well as minimal environmental impact. For this reason, new lines of work are proposed and other research groups are invited to be interested in this unknown green material.
       
  • Quality of Tectona grandis for sawn wood production

    • Abstract: Abstract: Forestry companies have invested in genetic improvement to increase wood production in a shorter amount of time. Thus, studies are needed to compare the properties of clonal and seminal wood materials. The objective of this study was to analyze physical and mechanical properties of Tectona grandis (teca) from clonal (C1 and C2) and seminal (S) origin and evaluate the yield and quality of sawn wood subjected to outdoor and oven drying. Genetic material was collected from six, 15-year-old trees. Clone C2 presented the lowest amount of bark, and 51% heartwood up to half the commercial height, while the heartwood of C1 and S went up to 25% of the height. The three materials did not differ statistically for maximum angular deviation, pith eccentricity, basic density, Janka hardness, anisotropy, commercial income of sawn wood and the presence of knots. After the drying processes, the bowing and crooking indexes were less than 5 mm.m-1, however, the seminal material showed a higher cracking incidence after outdoor and oven drying. In conclusion, the wood properties of the three materials are similar. In addition, the oven drying process is recommended.
       
  • Mechanical behaviour of Eucalyptus grandis shear walls. Experimental
           results vs the criterium of european standards

    • Abstract: Resumen: En este artículo se presentan y discuten los resultados de un proyecto orientado a investigar el comportamiento mecánico de muros de corte típicos de construcciones de entramado ligero y construidos con bastidor de Eucalyptus grandis (eucalipto) de la Mesopotamia Argentina. La investigación se llevó a cabo sobre 17 paneles, 15 de los cuales integraron 5 series con distintas configuraciones que cumplieron los requerimientos constructivos del Método A del Eurocódigo 5 UNE-EN 1995-1-1, y 2 con anomalías. Los ensayos se realizaron según la norma UNE-EN 594. La resistencia al descuadre determinada experimentalmente superó a la obtenida según el Método A en todos los paneles que cumplieron los requerimientos constructivos, ubicando del lado de la seguridad al valor calculado según las reglas europeas. Los resultados experimentales probaron una mayor variabilidad de la rigidez que de la resistencia y mostraron que los paneles que fallaron bajo cargas elevadas no siempre desarrollaron la resistencia esperada para deformaciones admisibles bajo cargas de servicio, indicando la conveniencia de focalizar sobre este aspecto en futuras investigaciones sobre estos sistemas estructurales.Abstract: This paper presents and discusses the results of a project aimed at investigating the mechanical behaviour of typical shear walls of light frame constructions and built with frame of Argentinean Eucalyptus grandis (eucalipto). The research was carried out on 17 panels, 15 of which distributed in 5 series with different configurations that met the construction requirements specified in Method A of Eurocode 5 UNE-EN 1995-1-1 and 2 presenting anomalies. All tests were carried out according to UNE-EN 594. The racking resistance determined experimentally exceeded that calculated according to the aforementioned Method in all panels that fulfil the construction requirements, placing the value calculated according to the European rules on the safety side. The experimental results confirmed a greater variability for the stiffness than for the resistance, and showed that the panels that failed under high loads do not always developed the expected resistance for allowable deformations under service loads, indicating the convenience of focusing on this aspect in future investigations on this structural system.
       
  • Cross laminated timber bonding quality for different Brazilian species and
           pressing levels

    • Abstract: Abstract: The proper choice of raw materials and manufacturing parameters for Cross Laminated Timber is essential to promote the proper bonding of the lamellas, aiming at their application in construction. However, few Brazilian species are currently used in the production of Cross Laminated Timber. The aim of this work was to characterize the bonding quality of four Brazilian reforestation species (Pinus elliottii (pino ellioti), Eucalyptus grandis (eucalipto), Toona ciliata (toona) and Acrocarpus fraxinifolius (lazcar)) in the manufacture of Cross Laminated Timber with two-component polyurethane adhesive and five different pressure levels (from 0,1 MPa to 1,3 MPa). Bonding quality was evaluated through delamination and glue line shear tests based on the European standard. Delamination was affected by the wood species, and the best adhesion occurred for the Cross Laminated Timber manufactured with Pinus elliottii (pino ellioti) and Acrocarpus fraxinifolius (lazcar) at the bonding pressure of 0,7 MPa. Cross Laminated Timber bonding pressure did not affect the percentage of wood in the shear test fractured surface, whereas higher density Cross Laminated Timber showed higher percentages.

    • Abstract: Abstract: The physical, mechanical, and thermal properties of Oriental beech (Fagus orientalis L.), which had been impregnated with the water-based, copper-containing Korasit KS material from the Alkaline Copper Quaternary group, were investigated in this study. The wood samples used in the investigation were impregnated with 3 % and 6 % aqueous solutions of Korasit KS. The modulus of rupture, thermal, and water absorption tests were performed on samples of Oriental beech after they had been impregnated. Oriental beech's modulus of rupture values decreased as a result of Korasit KS impregnation. Additionally, Oriental beech had lower modulus of rupture values at greater concentrations of Korasit KS. In every water absorption period, the water absorption values of the Oriental beech impregnated with Korasit KS were higher than those of the control group. Our results showed that Korasit KS impregnation enhanced thermal properties of Oriental beech. Moreover, higher concentration levels of Oriental beech yielded better thermal characteristics of Oriental beech.
       
  • Using acoustic testing to estimate strength and stiffness of wood-polymer
           composites

    • Abstract: Abstract This study used non-destructive testing with ultrasonic and stress wave propagation to evaluate bending strength and stiffness of wood-polymer composites. Twelve composite plate products were produced with different formulations of polymer matrix (high- and low-density polyethylene and polypropylene) and type and proportion of flour (coconut shell and wood). Mechanical and acoustic properties were influenced primarily by the type of matrix used in the composite. The greater the proportion of wood and coconut shell flour the higher the wave propagation velocity, stiffness, and strength. We found a correlation between mechanical properties (strength and stiffness) and wave velocity and stiffness coefficient. We also present linear regression equations of the stiffness and strength of the specimen as a function of wave velocity and stiffness coefficient obtained through non-destructive testing. For polypropylene and high-density polyethylene matrix composites, the stiffness coefficient provided a better estimate of stiffness, while for low-density polyethylene the wave velocity provided better results.
