X-ray micro-computed tomography of copper distribution in CA, ACQ and MCA treated wood and changes in microstructure of ACQ-treated southern pine following natural weathering
2024 - IRG/WP 24-20707
We hypothesized that X-ray micro-CT would be able to visualize: (a) the distribution of copper in CA-treated southern pine; and (b) microstructural changes in ACQ-treated southern pine exposed to natural weathering. Small blocks were removed from southern pine samples treated with CA and also southern pine treated with ACQ and MCA. Small blocks were also removed from ACQ-treated boards (flat and p...

Studies on the treatability of selected pine species and corresponding efficacies of a new non-biocidal treatment
2024 - IRG/WP 24-20721
Wood decay caused by fungi may reduce the service life of wood in outdoor applications. Since moisture conditions in wood occur as one of the most crucial parameters for fungal decay, chemical modifications, which affect the latter, may increase the resistance of wood against such organisms. Usually, pine sapwood is easier to chemically treat than heartwood, as the former generally shows good perm...

Virtual reality of wood protection
2024 - IRG/WP 24-20727
Virtual reality (VR) is a technology that allows people to explore and interact with computer generated environments using devices that stimulate different senses (sight, sound and touch). VR is mainly used for education, training and entertainment, but it also has the potential to provide new insights into scientific phenomena. We describe our work on the use of VR as a learning tool for students...

Natural weathering of modified pine and Eucalyptus woods by surface charring
2024 - IRG/WP 24-30801
Within various wood modification techniques, surface charring is anticipated to extend the lifespan of wooden components in building facades; however, visual deterioration of charred cladding materials has become a notable concern. This study, conducted through international collaboration, aimed to assess the resistance of bio-based facade materials to weathering in the Turkish climate. The natura...

Evaluation of vacuum borate treated spruce or pine CLT in an above ground protected test in southern Mississippi
2024 - IRG/WP 24-41001
Cross laminated timber (CLT) has become a popular wood composite in large building applications that were previously limited to concrete and steel. To extend service and prevent biological attack, chemical protectants are often applied to wood. Cross laminated timber panels are not typically treated, in part due to a lack of data on efficient and effective methods for treating large panels. Ther...

Evaluation of mass timber materials for military and commercial trailer decking
2024 - IRG/WP 24-41009
In this study, CLT trailer decking was manufactured to current military trailer decking specifications, verified using PRG320 performance criteria, and treated with either waterborne or oil borne wood preservatives. Preliminary results show adequate uptake of preservative solution and subsequent testing shows minimal effect due to treatment. Field durability tests are also being conducted of treat...
