| Deconstruction and demolition waste are a concern today because many timber components have a high resource value, providing both environmental and economic motivations for recovery and reuse. Reclaimed timber is therefore an important potential source of timber for new construction, and one for which nondestructive techniques have a key role to play. Assessment of timber properties by nondestructive measurements is not new. A lot of research has been carried out, and much work has gone into developing industrial devices for timber grading, but still some special considerations that should be analysed. This is especially true for less usual products such as reclaimed wood, and new wood from uncommon species or less usual sources. Large cross-section and long members are commonly found in existing structures. But it should be noted that these pieces have specific characteristics that make them different from smaller ones. On the other hand, various research studies have confirmed that timbers from dismantled structures with large crosssection have very good reuse potential. Therefore, this paper presents some considerations to be done during data collection and properties assessment in reclaimed timber, measuring its high reuse potential. It also covers the problem that current standards require strength grading on a basis that is not compatible with such products. | |
