20.500.12556/DiRROS-29418 Enhancing the fire resistance and fungal durability of solid wood via magnesium carbonate-based mineralization method Enhanced fire performance and durability of wood materials and products without harmful chemicals remains an important challenge. We propose a specific magnesium carbonate-based mineralization method for improving wood durability and fire resistance. During mineralization wood samples were impregnated with an aqueous solution of magnesium acetoacetate, which subsequently transforms within the wood to form various magnesium carbonate-based compounds, predominantly different hydrated and basic phases, the specific formation of which is influenced by factors such as wood anatomy and environmental conditions during post-treatment. Unlike traditional calcium carbonate, magnesium carbonates decompose at much lower temperatures, releasing both water and CO₂, which together contribute to enhanced flame protection through cooling and dilution of flammable gases. This treatment delayed ignition time by over 50% in two case studies, Norway spruce and European beech, compared to untreated controls. Additionally, such mineral-wood composites showed significantly lower mass loss when exposed to fungi, attributed to increased alkalinity compared to the untreated wood’s acidity. This dual-function mineralization approach offers an environmentally friendly alternative for improving fire and decay resistance and presents a non-hazardous biocide-free method that could replace certain conventional treatments. mineralization MgCO3 reaction to fire fungal durability environmentally friendly mineralizacija MgCO3 odziv na ogenj okolju prijazen true false true Elsevier Angleški jezik Slovenski jezik © 2026 The Author(s) Neznano 2026-05-18 11:59:28 2026-05-18 12:03:55 2026-05-19 03:54:40 0000-00-00 00:00:00 2026 0 0 str. 1-11 [article no.] 146355 Vol. 525 May 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-04-17 54 1879-0526 275810563 https://www.sciencedirect.com/science/article/pii/S0950061826012614 1 44170843-52a0-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44101 RAZ_Knez_Natasa_2026.pdf RAZ_Knez_Natasa_2026.pdf 1 66AE506657843CDACDBD7FB466955096 23b9cbd4eeca112be4170f17ba39f3ae88298a5497b1453f04bb3053033bbc7e a4400c07-52a0-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44102 http://hdl.handle.net/20.500.12556/DiRROS-22306 0 c6cdec28-52a0-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44103 Zavod za gradbeništvo Slovenije Dataset for the article Enhancing the fire resistance and fungal durability of solid wood via magnesium carbonate-based mineralization method 0 0 0
