Properties of thermal modified wood of Pinus pinaster, Pinus radiata and Pinus sylvestris from Galicia, Spain
2024 - IRG/WP 24-30800
This paper provides the results of a research about the properties of thermal modified wood of maritime pine (Pinus pinaster Ait.), radiata pine (Pinus radiata D. Don) and Scots pine (Pinus sylvestris L.) from Galicia, Spain, thermal treated in the industrial vacuum-heat autoclave plant of FINSA group in Galicia, Spain. These three pine wood species are used in different solid products but due the...

Citric acid and sorbitol treatment: A comparative study of Canadian and Norwegian species
2024 - IRG/WP 24-30806
Dimensional instability can reduce the competitiveness of wood in exterior applications such as cladding and decking. The objective of this work was to evaluate the dimensional stability of permeable and refractory softwoods from Europe and North America modified via a sorbitol and citric acid treatment. White spruce and Norwegian spruce, refractory species, and jack pine and Scots pine, relativel...

Manufacturing of bamboo hybrids with high strength, superior fire retardancy, and dimensional stability
2024 - IRG/WP 24-30808
Bamboo, renowned for its rapid growth, high strength-to-weight ratio, and eco-friendly attributes, has found extensive use in decorative building materials and glue-laminated beams. However, the inherent challenges of dimensional instability and flammability in natural bamboo restrict its broad application. This research introduces a range of environmentally friendly techniques aimed at producing ...

A novel treatment for increasing UV stabuility of wood based on citric acid and urea
2024 - IRG/WP 24-30811
Wood, a fundamental material in the Built Environment, faces challenges related to durability and weathering, notably UV degradation leading to colour changes. This study explored a novel treatment method utilising citric acid and urea to enhance the UV stability of wood. The reaction between these compounds forms fluorescent species and insoluble nanoparticles upon thermal treatment. Two treatmen...
