20.500.12556/RUL-127808 Assessment of wooden foundation piles after 125 years of service Buildings on piles have been constructed in Ljubljana since the Bronze Age. The piles were made of different types of wood. In the present study, piles that were erected about 125 years ago were investigated. Investors tend to renovate a building; therefore, the piles were analysed to assess the structural condition of the building. The building showed no signs of damage. To gain access to the piles, a 2 m thick layer of soil was removed. On-site, the following analyses were carried out: drilling resistance with a resistograph and a screw withdrawal test. Part of the piles was isolated and light microscopy, scanning electron microscopy, infrared spectroscopy, dynamic vapour sorption, density analysis, and chemical analysis were performed. Microscopic analysis revealed that the piles were made from the wood of Scots pine (Pinus sylvestris). The results indicate that the wood was severely degraded, mainly by soft-rot fungi and bacteria, resulting in a significant deterioration of its mechanical properties. piles waterlogged wood soft rot decay microscopy piloti arheološki mokri les glive mehke trohnobe mikroskopija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-06-23 10:27:14 2021-06-23 10:27:20 2023-03-21 14:14:22 0000-00-00 00:00:00 2021 0 0 13 str. iss. 2, art. 143 Vol. 12 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 1999-4907 10.3390/f12020143 48762115 RAZ_Humar_Miha_2021.pdf RAZ_Humar_Miha_2021.pdf 1 70BB95D48BFF845CBC9E9A9FC713623F afdf04045249282f318b0a4b7ac77d4e68f80bc46ef802d8794d043dcc5c4327 a3fa71b1-8d83-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153744 https://www.mdpi.com/1999-4907/12/2/143 0 89527938-8d83-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153743 Biotehniška fakulteta 0 0 0
