20.500.12556/RUL-174217 The durability, chemical and mechanical properties of 40 years old black locust posts This study investigated the performance of 40-year-old black locust (Robinia pseudoacacia) posts, previously employed in a vineyard. Wood from these posts was compared with wood from recently harvested wood to assess their potential for reuse. Visual inspection, hyperspectral imaging, chemical analysis and laboratory tests were utilised to evaluate decay, density, mechanical properties and extractive content. The older posts exhibited superior mechanical properties compared to the newly harvested wood. The older posts noted a higher density, indicating their superior quality. The heartwood of old black locust posts contained more extractives and phenolic compounds than the recently harvested wood. Minimal decay was revealed, classifying the wood into durability classes 1 or 2. No difference was observed in the inherent durability between the older and recent wood. The findings of this research demonstrate that 40-year-old black locust posts maintain exceptional durability and mechanical properties, rendering them suitable for reuse in outdoor applications. wooden posts vineyard wood decay mechanical properties polyphenols leseni koli vinogradi Robinia pseudoacacia les razkroj mehanske lastnosti polyphenols true false true Angleški jezik Slovenski jezik Članek v reviji 2025-09-30 08:01:33 2025-09-30 08:01:37 2025-11-19 03:45:52 0000-00-00 00:00:00 2025 0 0 Str. 1-9 iss. dec., [art. no.] e05221 Vol. 23 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 630*8 2214-5095 10.1016/j.cscm.2025.e05221 250980611 1-s2.0-S2214509525010198-main.pdf 1-s2.0-S2214509525010198-main.pdf 1 13F0B0A5671240F279F71516270AC81C be5c5e66dd3ff972f359b9a437ae90da58e643ae3c9a619eee47a9b48af00f01 072917d0-9dc3-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=218968 https://www.sciencedirect.com/science/article/pii/S2214509525010198 1 ba9a5136-9dc2-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=218967 Biotehniška fakulteta 0 0 0
