Effect of densification of Eucalyptus nitens and E. obliqua on moisture uptake, swelling, decay resistance, and fire performance
2022 - IRG/WP 22-40946
Some Australian Eucalyptus species that are abundantly available have low natural durability and poor resistance to fire. These same species are also extremely difficult to treat with preservatives or fire retardants using conventional pressure treatment methods due to a large proportion of refractory heartwood. The aim of this research was to understand whether thermo-mechanical densification had...

Multi-scale Experimental Study on Self-sustained Smouldering of CCA-treated Timber Poles
2023 - IRG/WP 23-40988
While it is accepted that appropriate treatment with chromated copper arsenate (CCA) will extend the design life of wood markedly, there are concerns regarding the effect of treatment on fire performance. Smouldering combustion in CCA-treated timber infrastructure can self-sustain, destroying the timber elements, as the chromium and copper present in the CCA can act as catalysts of the smouldering...
