In this study, the preliminary serviceability performance of cross-laminated timber (CLT) panels constructed from fibre-managed Eucalyptus nitens (E. nitens) was investigated via bending and vibration tests. Linear four-point tests were performed to determine stiffness deflection all CLT under loads. The dynamic response tested using a basketball an accelerometer. fundamental natural frequencie...

Medium-density fiberboard (MDF) was developed from Durio zibethinus (durian) husk using urea formaldehyde (UF) as binder. The output will be applied an automotive panel, realigning the conventional application of MDFs. Fibers were recovered husk, undersize 10 mesh screen used for board production. optimal conditions determined by different mixing ratios UF with water and varying pressing pressu...

• X-ray scanning, as a non-destructive detection method, can test the pore structure of UHPFRC. In this paper, negative effect mechanism steel fiber on compressive properties UHPFRC is analyzed through flowability 36 UHPFRCs with different volume fractions and aspect ratios, scanning used to compare fresh hardened Based positive effects fiber, combined analysis data, prediction semi-empirical f...

The modulus of elasticity Youngs modulus E is a material property, that. From the Hooks law the modulus of elasticity is defined as the ratio of the stress to.modulus of elasticity of the cultured SC cells examined in this study, in central, non-nuclear regions, ranged between. Johnson B.all require an effective E, the Youngs modulus or elastic modulus, to quantify. Elastic moduli, such as the ...

an understanding of the strength of rice grains as affected by moisture content and temperature is important for analysis and prediction of cracking and/or breakage behavior during handling and processing. further, the magnitude of these properties at various moisture contents and temperatures is needed for the accurate design of milling machinery so that grain damage is minimized. to determine...

in this research, the possibility of using high percentage of lignocellulosic fibers in making natural fiber-thermoplastic composite was studied. three weight percentages of bagasse flour namely 40, 55 and 70 percents were chosen. mapp was used as coupling agent at two weight percentages of pp, namely 0, 4 and 6 percents. tensile strength was measured applying instron 6025. the results showed t...

The mechanical properties of plantation Eucalyptus Nitens timber are currently assessed by applying visual stress grading (VSG) designed for the sawn from mature and do not represent actual characteristics resource. However, well-known limitation VSG application this resource led to discovery other methods grade its relevant structural grade. There is potential hardwood plantations in Australia...

The application of waste materials in the concrete composite is a great contribution to preserving natural resources and enhancing sustainable greener development construction industry. This study used Palm Oil Clinker (POC) steel fibers manufacture high-strength lightweight (HSLWC). POC basically byproduct palm oil industry, which was utilized as coarse aggregates supplementary cementitious co...

the application of stepwise multivariate-linear regression models for determination of particleboard properties based on structural factors was studied. poplar (populus alba), beech (fagus orientaleis) and hornbeam wood (carpinus betulus) with dry density of 460, 630 and 790 kg/m3,respectively, were used as raw materials. three levels of boards target density (520, 620 and 720 kg m-3) and urea ...

medium density fiberboard (mdf) was produced using moist depithed bagasse stored dry or wet. the duration of storage for either method varied between 0 to 4 months. two steaming temperatures of 175c and 185c were also used. mdf boards were produced in the laboratory and the common mechanical and physical properties were measured and compared. results showed that an increased steaming temperat...
