Abstract

Radiography is a method of non-destructive evaluation of the quality of construction wood in order to detect the defects due to natural degradation. The objective of this study was to investigate the assessment of poplar (Populus deltoides) and beech (Fagus orientalis) wood defects arising from the decay using X-ray non-destructive method. In this study, for each of species, uncoated and coated by acid catalyzed lacquers and nitrocellulose lacquers samples were used. decay resistance test was performed according to modified ASTM D1413 standard. The decaying of the woods was done for the periods of 1, 2 and 3 months using Coriolus versicolor fungus at laboratory conditions. After each of these periods, for the decay of the samples, X-ray imaging using an imaging at the cross, tangential, and radial directions was done. Results of weight loss confirmed the presence of decay. The results showed that after 1, 2 and 3 months of exposure to fungus, fungal degradation lead to weight loss in the coated and uncoated samples. So that, the weight loss caused by decay in beech was less than poplar samples. As well, the weight loss of uncoated was less than of coated samples, which was also statistically significant. The X-ray results of uncoated and coated samples at the cross, tangential, and radial directions indicated that decay has more impact on beech wood in comparison to poplar wood structure. The study as well showed that the protective layer provided a partly barrier for decay destruction in these samples.
