Surface treatment of cross-laminated timber to improve water repellency and UV resistance
2024 - IRG/WP 24-20716
Cross-laminated timber (CLT) has emerged as a revolutionary building material, offering a sustainable alternative to traditional construction methods. By layering and bonding multiple layers of wood at right angles, CLT creates a robust and versatile structural element capable of supporting significant loads while promoting eco-friendliness and design flexibility. However, despite its numerous adv...

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...

Assessment of historical pilings from Lisbon
2024 - IRG/WP 24-41004
The renovation and rebuilding of areas in Lisbon has led to work on buildings constructed in the Pombaline downtown district. These buildings were constructed on wooden pilings, as a means of stabilising unstable soils and transfer the loads from buildings to soils with adequate bearing capacity. These methods also increased the resilience of the reconstruction works to future possible earthquakes...

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...

Performance of Douglas-fir cross laminated timber (CLT) subjected to elevated humidity in a ground proximity field test for 6 years
2024 - IRG/WP 24-41010
The ability of insecticidal soil drenches or spray-on insecticide/fungicide treatments to protect mass timber elements exposed in a high moisture environment but out of direct soil contact was assessed using a modified AWPA ground proximity test established in 2017. Three-ply Douglas-fir CLT pieces measuring 305 x 355 x 105 mm (L x H x W) were installed at the Harrison Experimental Forest (HEF) (S...

Durability of Malaysian plybamboo to mold
2024 - IRG/WP 24-41014
Durability of 3-layer plybamboo fabricated from two Malaysian bamboo species, Gigantochloa levis (beting) and Gigantochloa scortechinii (semantan) using three different adhesives - urea formaldehyde (UF), melamine urea formaldehyde (MUF) and phenol resorcinal formaldehyde (PRF) was evaluated in this study. Samples were exposed to the mold, Aspergillus brasiliensis for 4-week following the ASTM D44...

Evaluating the potential for re-using timber from deconstructed sea defence groynes from the Bournemouth groyne field
2024 - IRG/WP 24-50397
In the shadow of a looming climate crisis, the modern age construction industry is evolving. The for implementing sustainable practices has never been greater and the potential role of the circular economy is front and centre. It can play a pivotal role in transforming the industry by promoting sustainable practices which emphasise the need to reduce consumption of natural resources. Re-using timb...

Timber circularity discussion: Waste hierarchy and prioritising reuse opportunities!
2024 - IRG/WP 24-50398
By following the waste hierarchy and prioritising reuse opportunities first before resorting to disposal in landfills, we can effectively sustainably manage timber resources. This approach helps to conserve natural resources, reduce energy consumption, minimize greenhouse gas emissions, and minimize the overall environmental footprint associated with timber production and disposal. It also promote...
