The impact of common fire retardancy salts and minerals on further properties of wood
2025 - IRG/WP 25-30821
Wood has become an increasingly important construction material. To ensure fire safety, fire retardants are widely applied. Recent research focuses on environmentally friendly fire retardants with strong fixation. Phosphate-based salts like diammonium hydrogen phosphate show high fire protection potential but are highly leachable due to their good water solubility. As a newer trend mineralisation ...

Mineral-wood composites with improved fire properties and durability prepared through MgCO3-based mineralization
2025 - IRG/WP 25-30823
New mineral-wood composites that demonstrate improved fire properties and higher resistance to selected fungi have been prepared using an environmentally-friendly mineralisation process involving impregnation with an aqueous magnesium acetoacetate solution. MgCO3-based compounds are formed in situ, deep within the wood’s structure. We show that the new mineralisation method overcomes wood’s lo...

Effect of Deep Eutectic Solvent Pretreatment on Properties of Densified Wood
2025 - IRG/WP 25-30824
Densified wood is preferable for structural applications because of its excellent mechanical properties and sustainability, but the fixation of its compression deformation and the prevention of water-induced mechanical deterioration remain challenging. Herein, an eco-friendly and highly efficient method was designed for producing dimensionally-stable densified wood, including deep eutectic solvent...

Enhancing strength, fire and biological resistance of wood through structural and chemical modification
2025 - IRG/WP 25-30831
Wood, a renewable and versatile biopolymer, has been a fundamental material to construct traditional and advanced composites for building construction, furniture, transparent composites, and various other applications. Despite its many advantages, including its aesthetic appeal, workability, and relatively low cost, wood possesses inherent limitations such as susceptibility to biological, flame an...

Effect of biodiesel-containing solvents on the performance of Copper Naphthenate and Pentachlorophenol: 118-month assessment and depletion analysis
2025 - IRG/WP 25-41022
Solvent systems are incredibly important in determining the performance of oilborne wood preservative systems and they can cause early failures in commodities treated with an otherwise effective preservative system. It is important to assess new solvent performance with oilborne preservative systems to ensure these systems continue to function with the changes. One solvent/preservative combination...

Effect of photodegradation on fungal colonization on wood during initial stage of brown-rot decay
2025 - IRG/WP 25-41024
Photodegradation and decay may happen simultaneously on wood under many exposure conditions. The aim of this study was to explore the effect of photodegradation on fungal colonization during initial stage of brown-rot decay of wood. For this purpose, southern pine (Pinus spp.) wood was exposed to accelerated UV weathering for different durations, and then decayed by a brown rot fungus (Gloeophyllu...

Analysis of A Wooden Structure Damaged in a Fire – The Wooden Granary at Zaprice, Kamnik
2025 - IRG/WP 25-41049
Zaprice Open-Air Museum in Kamnik, Slovenia, features several granaries dating to the early 19th century, forming part of the national Cultural Heritage Register (EID: 1-09881). One of the two-chamber wooden granaries, constructed in 1828, suffered significant fire damage in December 2024. The objective of this study was to evaluate the extent of the damage, assess the structural integrity, and id...
