Sažetak
Different concentrations of chemicals in water solution, final temperatures and curing periods were used for common beech wood modificiation with Citric acid (CA). In distilled water (at 60 °C) extracted specimens were impregnated with citric acid (CA) water solutions of different concentrations with phosphate catalyst. After impregnation, specimens were air-dried and then cured at elevated temperatures using different regimes. The effects of different modification regimes were assessed through the values of weight percentage gain (WPG), anti swelling efficiency (ASE), mass loss caused by leaching (MLL) and leachability coefficient of gained mass (LCM). Optimal combination of modification parameters was chosen for each of mentioned properties and then only one optimal combination of modification parameters was selected.
