RT Journal Article SR Electronic A1 Holan, Jiří A1 Merenda, Lukáš T1 Selected mechanical properties of modified beech wood JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 56 IS 1 SP 245 OP 250 DO 10.11118/actaun200856010245 UL https://acta.mendelu.cz/artkey/acu-200801-0029.php AB This thesis deals with an examination of mechanical properties of ammonia treated beach wood with a trademark Lignamon. For determination mechanical properties were used procedures especially based on ČSN. From the results is noticeable increased density of wood by 22% in comparison with untreated beach wood, which makes considerable increase of the most mechanical wood properties. Considering failure strength was raised by 32% and modulus of elasticity was raised at average about 46%.
