Surface treatment of cross-laminated timber to improve water repellency and UV resistance
2024 - IRG/WP 24-20716
Cross-laminated timber (CLT) has emerged as a revolutionary building material, offering a sustainable alternative to traditional construction methods. By layering and bonding multiple layers of wood at right angles, CLT creates a robust and versatile structural element capable of supporting significant loads while promoting eco-friendliness and design flexibility. However, despite its numerous adv...

Evaluation of the water exclusion ability and inherent bioactivity of heartwood against decay in Japanese and European wood species via above-ground exposure and water absorption tests
2024 - IRG/WP 24-40998
The natural durability of wood has been thought to mainly depend on bioactive extractives and the water exclusion ability. To clarify the contribution of each factor to wood durability, above-ground exposure tests were conducted on Japanese and European wood species. A double-layer test was carried out using heartwood specimens of four wood species, i.e., Japanese cedar, Japanese cypress, Scots pi...

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, ...
