Experimental study on compressive strength performance of cross laminated timber with biodeterioration damage
2019 - IRG/WP 19-40883
The mass timber construction has attracted attention around the world. The reasons are due to the environmental impacts and the potential of the strength performance and quantity of the wood. Nowadays, CLT is one of the most important materials for the timber constructions. If we use CLT as a building material, we should consider the biodegradation risk for long time use. From an estimation of fut...

Penetration pathway of oilborne preservative in heartwood of Japanese larch (Larix kaempferi)
2019 - IRG/WP 19-40886
The liquid permeability of Japanese larch (Larix kaempferi) wood is extremely low, especially in the heartwood. It is difficult to achieve the penetration of wood preservatives, which is specified by standards, with pressure treatment of waterborne preservatives. Recently, the protection treatment with an oilborne preservative called “deeper penetration treatment” is commercially available, wh...
