Wood kiln drying. Simple process of material treament or soft method of preservation? (Le séchage arificiel du bois. Simple opération de traitement du metériau ou méthode douce de préservation?)
1993 - IRG/WP 93-50001-14
Among the processes enabling to extend wood durability, kiln drying can be considered as a treatment and soft preservation method. Dry woods are naturally durable provided they are not subject to important retaking of the moisture. Drying thanks to the application of temperatures from 50 to120°C enable to execute a thermic treatment which kills grubs and mushrooms to ensure a sterilization that c...

Effect of Moisture Cycles and Timber Treatment on the Performance of Screwed Connections
2023 - IRG/WP 23-20694
The impact of moisture in timber structures is associated with the deterioration of timber, and loss of mechanical performance. Methods have been developed to treat timber using chemicals to inhibit deterioration, however, water intrusion has much more immediate effects on the mechanical properties of timber associated with swelling and shrinkage of the wood. The effects of moisture on the mechani...

Impacts of elevated moisture levels and subsequent drying on screwed
2023 - IRG/WP 23-40970
Mass timber (glue-laminated timber, cross laminated timber (CLT) and laminated veneer lumber) are increasingly used in mid-to high rise structures in Australia where the climate is mainly sub-tropical with elevated moisture levels and high termite risk. Moisture intrusion poses a major challenge anywhere but becomes more critical under these conditions. Untreated/non-durable materials are consider...
