The Effects of Some Fire Retardant Chemicals on the Decay Resistance of Medium Density Fiberboard (MDF)
2010 - IRG/WP 10-30536
The objective of this study was to determine the decay resistance of Medium Density Fiberboard (MDF) treated with 5% and 10% concentration of various fire retardant (FR) chemicals. Experimental panels were produced using by melamine-urea-formaldehyde (MUF) resins having 10%, 15% and 20% of melamine content. MDF specimens were subjected to decay resistance test performed according to modified EN 11...

A Review of Radial Flow of the Refractory Softwoods: An Example of Sitka Spruce
2011 - IRG/WP 11-40564
As one of the refractory softwood species, the major problems in the preservative treatment of spruce based on the radial flow relate to the anatomical structure of the wood material. The most important morphological features influencing this were the amount of the nature and the condition of both ray tracheids and ray parenchyma cells, and the cross-field pits in particular. The conducting pathwa...

WOOD: its importance in our life
2012 - IRG/WP 12-40583
As it is described by Hoadley (1980) and Tsoumis (1991), wood is an organic material yielded by trees which increase in diameter by the formation of new woody layers which envelop the entire stem. Wood has served man since he appeared on Earth (as a fuel and/or as a construction material for making houses, tools, weapons, furniture, packaging, paper, and artworks). It is important to appreciate th...

Comparison of moisture loss and its increment during the rehearsal process based on natural drying and water soaking application with or without sealing the trial discs of Common black poplar (Populus nigra L.)
2013 - IRG/WP 13-40639
This study was subjected to be set up to prove the pattern of moisture loss and moisture increment within the same wood samples prepared as the discs (30x23±3 cm diameter) with or without the bark intact during drying and in the duration of the water soaking application. In this concept, wood was exemplified by Common black poplar (Populus nigra L.) of the five 12 year old trees that are grown in...

Evaluation of vessel features on physical and mechanical properties of wood of Common black poplar (Populus nigra L.) grown at different elevations in the region with a continental climate
2014 - IRG/WP 14-40656
This study essentially examined the effect of elevation on the anatomical structure, and the physical and mechanical properties of Common black poplar (Populus nigra L.) wood. The scope of the study was to observe the variability of vessel element features on physical and mechanical properties of Common black poplar (Populus nigra L.) in relation to habitat at different elevations. For this purpos...

Suggestive remarks for designing of experimental samples and trial devices to treat wood by pre-vacuumed immersion method
2019 - IRG/WP 19-40862
This study was conducted to test the impregnability of wood material according to the pre-vacuumed immersion process and to reveal the usability of cylindrical (plug) samples in impregnation experiments in addition to the cuboid or cubic samples. In this context, cuboids were prepared 30 mm in length, 20 mm in width and 20 mm in thickness, whereas plugs were prepared radially and longitudinally wi...
