In-ground field test of scots pine (Pinus sylvestris L.) sapwood and heartwood
2004 - IRG/WP 04-30336
Scots pine (Pinus sylvestris L.) sapwood and heartwood stakes treated with CCA-C and creosote were tested for one- year in a field plot in Bartın region in Turkey.
Scots pine heartwood stakes had lower preservative retention than sapwood stakes. Bending strength of the stakes was decreased after impregnation and one-year field test. While the bending strength of untreated sapwood was 93....

Variation of commercial timbers from Turkey in resistance to marine borers as assessed by marine trial and laboratory screening
2008 - IRG/WP 08-10668
Commercial timbers from Turkey used in coastal construction and boat building were tested for their resistance to marine wood-boring invertebrates in a marine trial and in a laboratory screening test. The timbers tested were beech (Fagus orientalis), oak (Quercus petraea), chestnut (Castanea sativa) and Scots pine (Pinus sylvestris). The marine trial was conducted over a period of 5 months at Mers...

Natural Durability of Some Heartwood from European and Tropical African Trees against Marine Organisms
2009 - IRG/WP 09-10682
This study aims to investigate the natural marine durability of some tropical and domestic wood species in marine environment. A total of 33 tree species, comprising 18 European and 15 tropical originated trees were exposed to marine conditions in 6 meters depth for a period of 14 months at east and west Black sea, Mediterranean, Aegean, and Marmara coasts. The results indicated that wood species...

Fouling and Boring Organisms Deteriorating Various European and Tropical Woods at Turkish Seas
2010 - IRG/WP 10-10741
This study aims to investigate the diversity of fouling and boring organisms damaging wood material at Turkish coasts. Trials were carried out at six harbour sites throughout the seas surrounding Turkey. Wood samples were hanged down at a depth of six meters in the sea, for a period of one year. Identification of the organisms obtained from wood plates revealed the presence of five wood borer and ...

Accelerated Weathering Performance of Impregnated Wood Samples Coated with Zinc by Means of Plasma-Assisted Particle Deposition
2016 - IRG/WP 16-30682
Many different methods are currently applied for wood protection against outdoor conditions. The most important of these is the process of impregnation with liquid substances. However, this kind of wood preservatives cannot provide a long-term protection of wooden surfaces. Weathering-resistant surfaces can be obtained by applying UV absorbing agents. In this study, the influence of zinc particles...

Changes in topochemistry and mechanical properties of Beech (Fagus orientalis L.) by natural fungus infestation
2022 - IRG/WP 22-10986
Beech is one of the major hardwood species in Europe. It is, however, highly susceptible to fungal attack both in the fresh state and during the storage. Understanding the alteration in chemical and mechanical properties of beech wood during the initial degradation state can lead to improved raw material utilization. Therefore, UV-microspectrophotometer (UMSP) and High-Performance Liquid Chromatog...
