Performance of treated Malaysian semantang bamboo (Gigantochloa scortechinii) - field and laboratory durability evaluation
2023 - IRG/WP 23-30788
Field performance of sematan bamboo, Gigantochloa scortechinii was evaluated under the Malaysian tropical climate, along with laboratory evaluation to white-rot fungi and mold. Starch was removed from the bamboo by submerging the bamboo in the river for 6-8 weeks, kiln-dried and cut to 300 mm (L) round bamboo and 25 mm (W) x 50 mm (L) stripe for the field and laboratory test respectively. Bamboo w...

Evaluation of the efficacy of silver nanoparticles and chitosan oligomer composites as poplar wood protective treatments against termites
2023 - IRG/WP 23-40963
Populus × euramericana ‘I-214’ (poplar) is a fast-growing species widely distributed throughout the world, and in the Castile-Leon region of Spain it accounts for more than 50% of all plantations. Its wood is becoming increasingly appreciated, yet its low durability against xylophagous agents —termites being one of the most aggressive and destructive in warm climates— continues to be a li...

Evaluation of the effectiveness of soaking of high-temperature plywood in low-temperature oil-based wood
2023 - IRG/WP 23-40991
We conducted a preliminary investigation to determine if soaking high-temperature plywood in a low-temperature preservative solution could achieve deeper penetration of the preservative, even in plywood made with refractory wood species such as Japanese larch. Specimens cut from commercial plywood (Japanese larch) were stored at various temperatures before being soaked in the preservative solution...

Time-lapse evaluation of Aureobasidium pullulans growth on selected lignin derivatives and chitosan
2024 - IRG/WP 24-11032
Wood, often referred to as the “building material of the 21st century”, has gained recognition as an attractive alternative to several traditional building solutions. To enlarge the application of wood, several properties including biotic and abiotic degradation resistance need to be improved. Consequently, new solutions are available on the market that ensure expected properties and functiona...

Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...

Evaluation of the water exclusion ability and inherent bioactivity of heartwood against decay in Japanese and European wood species via above-ground exposure and water absorption tests
2024 - IRG/WP 24-40998
The natural durability of wood has been thought to mainly depend on bioactive extractives and the water exclusion ability. To clarify the contribution of each factor to wood durability, above-ground exposure tests were conducted on Japanese and European wood species. A double-layer test was carried out using heartwood specimens of four wood species, i.e., Japanese cedar, Japanese cypress, Scots pi...

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...
