Odpornost starega lesa iz kozolca proti lesnim glivam : diplomsko delo = Decay resistance of wood from hayrack against wood decay fungi : B. Sc. thesisĆosić, JurePodjetje M Sora je v bližini Žirov podrlo dotrajan lesen kozolec v Sedejevi dolini v vasi Opale. Iz pridobljenega lesa razvija in izdeluje nova lesena okna. Za namen raziskave smo iz starega lesa ... kozolca odvzeli okvirno 1 m dolge vzorce tramov, leg in špirovcev. Večina odvzetih vzorcev je bila iz smrekovega lesa, en vzorec pa iz lesa češnje. Iz večjih vzorcev smo pripravili vzorce za testiranje odpornosti proti lesnim glivam po standardu (EN 113) in vzorce za testiranje mehanskih lastnosti. Pri mehanskih testiranjih smo določali upogibno in tlačno trdnost. Določili smo gostoto lesa, izgubo mase, vlažnost vzorcev po izpostavitvi glivam, upogibni elastični modul, tlačno trdnost in upogibno trdnost. Rezultati odpornosti lesa na glive bele in rjave trohnobe so pokazali, da je izguba mase vzorcev, izdelanih iz starega lesa iz kozolca primerljiva z izgubo mase kontrolnih vzorcev, izdelanih iz sveže posekane smrekovine. Do podobnih ugotovitev smo prišli tudi pri mehanskih testih. Glede na dobljene rezultate naše naloge lahko zaključimo, da ima star les iz kozolca velik potencial za ponovno uporabo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
