Book excerpt: Mass timber construction is rapidly growing in North America, given its versatility and performance. Additionally, wood has a high strength to weight ratio and low environmental impact in contrast with other construction materials. Nevertheless, durability is a significant concern that needs to be addressed for the advancement of mass timber construction. Extreme care is required to protect members from exposure to high moisture environments while ensuring long-term durability. This project thus focuses on improvements of wood’s longevity by combating two main issues: dimensional stability and decay resistance to biological organisms. At the same time, a sustainable approach is considered while utilizing small-diameter logs, which optimizes forest industry products. This is all achieved with the fabrication of Cross Laminated Strand-Veneer-Lumber (CLSVL) out of thermally modified wood strands. State-of-the-art concepts and technologies are implemented in the treatment process, fabrication, and assessment of the material. At first, wood strands are treated at different temperatures to understand its implications. A look at wettability, water sorption, and wood structure is used for this analysis. Furthermore, a series of macro-level mechanical benchmark tests in thin plies are conducted, such as internal bonding and bending. Later, accelerated decay tests are done to assess the improvement of wood’s resistance to rot fungi. Finally, these analyses are used to systematically understand the thermal modification to obtain the best performing material to be used in the fabrication of mass timber as CLSVL, where its uni-axial out-of-plane bending performance is evaluated.
