Effects of phosphoric acid and diammonium phosphate treatments on the physical and fire-retardant properties of five selected Nigerian wood species
2024 - IRG/WP 24-20713
Wooden products in buildings are major sources of fuel for fire outbreaks. Effects of phosphoric acid and diammonium phosphate treatments on the physical and fire-retardant properties of wood species commonly used in buildings were evaluated. The timber species utilized in this study were sourced from the sawmill sector located in Akure, Nigeria, encompassing Brachystegia laurentii, Khaya ivorensi...

Preservative properties of boron-treated paulownia wood
2024 - IRG/WP 24-20729
This research was performed to investigate the preservative retention properties of paulownia wood treated using boric acid/borax at mass ratio of 1:1.8. Different portion of paulownia wood (top, middle, bottom) were used as a sample throughout of this study. In the treatment process, the paulownia wood was dipped in the 1% boric acid/borax solution for 1, 24, 72, 120 and 240 hours to achieve requ...

Bio-durability and weathering performances of cardanol-treated wood
2024 - IRG/WP 24-30809
Cardanol is an excellent insecticide, fungicide, and termiticide derived from thermally treated cashew nutshell liquid (CNSL) and has been extensively explored in the chemical industry and for medicinal uses. However, its potential for wood protection remains unexplored. This study aims to understand the bio-durability and weathering properties of cardanol-treated wood. The southern pine and yello...

Assessment of hydrophobic properties of acetylated and furfurylated Korean wood species
2024 - IRG/WP 24-30812
To increase the utilization of Korean wood species, the hydrophobic properties of the most commonly used wood species in Korea were compared according to wood modification. Pinus densiflora (sapwood and heartwood) and Larix kaempferi (heartwood) were selected as test wood species, and Pinus radiata (sapwood) was selected as the control wood species. The wood modification was performed by acetylati...

The durability and mechanical properties of 40 years old Black locust poles
2024 - IRG/WP 24-11042
This study investigates the durability and mechanical properties of 40-year-old black locust (Robinia pseudoacacia) poles harvested from a vineyard in Slovenia. Wood from these poles was compared to recently harvested black locust wood to determine possible reuse options. Visual inspection, hyperspectral imaging, and laboratory tests were conducted to assess decay, density, mechanical properties, ...
