Comparison of AE-apparatus for detection of activity of Old house borer larvae, including reality check
2021 - IRG/WP 21-10981
As part of the German funded project ‘InsectDetect’ comparative measurements were done with three different Acoustic-Emission-(AE)-apparatus on 14 pine beams in order to assess presence of active attack by the Old house borer (Hylotrupes bajulus (L.)).
In all beams active attack was measured, though in varying intensity. This was corroborated by completely dissecting 10 of the beams. All thre...

Green approach in wood mineralization for improvement of fire properties
2022 - IRG/WP 22-30769
Various treatments have been developed in order to improve fire properties of wood. Because the use of some flame retardants can release toxic compounds in the event of a fire, leading to poisoning or even death of people from smoke inhalation, the use of no-toxic and more ecologically acceptable flame retardants is preferable. Mineralization of wood with the incorporation of carbonates has proven...

Improving wood durability by mineralisation and thermal modification
2022 - IRG/WP 22-40948
A significant increase in the fungal durability of wood was achieved by using a modification procedure combining two environmentally friendly methods: thermal modification and mineralisation. It offers an ecological alternative to other biocidal treatments. European beech (Fagus sylvatica) and Norway spruce (Picea abies) were selected as model wood species and exposed to four different fungi: Gloe...

Field test methods as long-term aging – report of selective wood properties
2023 - IRG/WP 23-40962
Wood samples from a long-term field test are a valuable compendium of information about the material in the context of its aging processes. In the current work, wood samples from the round-robin test within the ECOMOD project were used as a material for the natural aging process (III and IV class of utility). The research scope was to determine selected properties of this wood which can be partial...

Utilising novel service life prediction methods for robust and precise Life-Cycle-Costing (LCC)
2023 - IRG/WP 23-50384
Life-Cycle-Costing (LCC) is one of the basic indicators for the assessment of sustainability and cost effectiveness in construction applications. Project WoodLCC was thus conceived to enable LCC through input from models for detailed service life planning of wooden components and buildings. The project is a continuation of the service life planning research conducted in Europe over the last three ...
