Physical, durability and chemical characterization of Gmelina arborea (Roxb.) wood treated with lactic acid
2024 - IRG/WP 24-30803
The increase in demand for durable wood has drawn attention to the use of fast-grown plantation species across the globe. Chemical modification was used to treat Gmelina arborea wood with lactic acid for property enhancement. The treated samples were obtained from two different ages of 15 and 10 years and sawn into (20 x 20 x 60) mm and (20 x 20 x 20) mm for physical, durability and chemical chara...

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...

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...
