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...

Effect of long-term immersion in fresh and salt water on mould growth on Scots pine (Pinus Sylvestris L.) wood
2020 - IRG/WP 20-10962
Wood exposed outdoors will eventually be degraded by fungi, depending on exposure and material characteristics. Numerous wooden constructions in the Røros municipality have existed since the 17th century, but wood used in recent repairs have decayed faster than expected. Before 1970 timber was mainly transported by log driving or rafting, and the logs were immersed in water for longer or shorter ...

Results of the resistance of acetylated wood against marine borers at three Italian sites after five years of sea immersion
2022 - IRG/WP 22-10994
The aim of this research was the determination of resistance of acetylated wood against marine decay in use class 5 (EN 335) in temperate sea waters. The resistance of acetylated Pinus radiata (radiate pine) in solid and medium density fibreboard (MDF) panels is compared with that of the untreated Scots pine, radiata pine and other untreated wood of European species such as Fagus sylvatica (Europe...

Time-lapse evaluation of Aureobasidium pullulans growth on selected lignin derivatives and chitosan
2024 - IRG/WP 24-11032
Wood, often referred to as the “building material of the 21st century”, has gained recognition as an attractive alternative to several traditional building solutions. To enlarge the application of wood, several properties including biotic and abiotic degradation resistance need to be improved. Consequently, new solutions are available on the market that ensure expected properties and functiona...

Intra-species variability of moisture dynamics in wood
2024 - IRG/WP 24-11040
Moisture dynamics of wood and wood-based materials play a major role in wood durability against different decay organisms. Their impact becomes particularly evident when wood is exposed, but not permanently wet. To date, however, this has only been taken into account indirectly and therefore inadequately when testing the durability of wood. While test methods are available, for example to determin...

On the use of miniaturized wood specimens in fungal decay experiments – mini-blocks versus EN 113 test specimens
2024 - IRG/WP 24-11044
Preliminary evaluation and classification of wood durability against decay fungi using laboratory monoculture experiments has been a longstanding practice because these tests offer quicker results than field tests. Various methods, including miniaturized specimen formats and different incubation periods, have been explored to expedite decay processes and assess wood preservation efficacy. The 'min...

International joint field trial on the moisture performance of wood – Set up and first results
2024 - IRG/WP 24-40996
Wood durability to decay stems from its inherent resistance to fungi resistance to fungi. In this regard, wood's ability to withstand moisture uptake plays an important role as the lower threshold for wood decay is a moisture content of 25%. However, the aspect of moisture resistance is not yet sufficiently emphasized as a durability factor, both in the assessment of durability as a material prope...

Exploring the migration of creosote in freshwater environments: A study on treated wood immersion
2024 - IRG/WP 24-50392
Creosote is used as a wood preservative in aquatic environments and contain polycyclic aromatic hydrocarbons as active ingredients. It is critical to quantify the impact of these commodities on the environment to ensure specific uses of these commodities complies with federal and state regulatory standards for water bodies. This study explores Polycyclic Aromatic Hydrocarbons (PAH) migration patte...
