Evaluation of Natural durability of Horn beam (Carpinus betulus) wood against Coriolus Versicolor in case of Treated with CCA (Tanalith c)

In this study, the influence of the fungus (Coriolus versicolor) on the durability of Horn beam (carpinus betulus) in natural state and treated with CCA (Copper/Chromium/Arsenic) was evaluated. CCA is a kind of water borne preservatives that was used to treat specimens under vacuum and pressure (Bet...
