Study of the degradation of retified wood through ultrasonic and gravimetric techniques
1994 - IRG/WP 94-40030
One of the non-polluting processes that increase the natural durability of wood is a thermal treatment in an atmosphere poor in oxygen, producing what is normally denominated "retified wood". In this study the validity of a non-destructive technique (ultrasound) in order to determine the biodegradation suffered by wood across time has been studied. For this reason, the behavior of a wood species (...

Evaluation of the natural durability and ultrasonic method for decay detection of some european hardwood and softwood species
2004 - IRG/WP 04-10537
This paper presents the first part of an investigation on the natural durability of mixed plywood made of durable and non durable plies from the following selected timbers : Cedrus atlantica, Cupressus sempervirens, Castanea sativa, Populus sp. I 214 and Fagus sylvatica.
In order to carry out this study, the natural durability of the massive wood used to manufacture the plywood panels was asses...

Application of an Ultrasound-based Instrument to Evaluate Condition of Drywood Termite Infested Timber Components
2022 - IRG/WP 22-11000
The characteristics of ultrasound waves propagation from non-destructive ultrasound-based instrument on drywood termite infested wooden components were investigated. Features of wave propagation such as time-of-flight, velocity, and peak energy on three orthogonal wooden plane (longitudinal, radial, and transversal) were studied. The wooden components used on this study came from a traditional woo...

Ultrasound as an alternative treatment in wood protection
2023 - IRG/WP 23-40973
Bursaphelenchus xylophilus Nickle 1970 is probably the most important nematode of the pine, affecting coniferous forest masses, and that has forced the European Union to take measures to prevent its propagation. In sawmills, wood is currently subjected to heat treatment in accordance with the International Standard for Phytosanitary Measures No. 15 (ISPM 15 2019). This standard contemplates three ...
