Evaluation of an optimized industrial process aiming to improve the natural durability and mechanical behavior of bamboo for outdoor use
2011 - IRG/WP 11-40554
Mao Bamboo (Phyllostachys pubescens) is characterized by high contents of sugar and starch and by high hygroscopicity, which makes it susceptible to biodegradation, and specifically to fungal decay. Still, many bamboo based products regularly enter the European wood construction market, competing with traditional solid wood products used for outdoor decking and cladding. The performance of a heat ...

Micromorphological and chemical characteristics of waterlogged archaeological bamboos excavated from the Yellow Sea
2012 - IRG/WP 12-10785
Bamboos have widely used as documentation material in Far Eastern countries such China, Korea and Japan. In particular, bamboo slips as documentation material were extensively used even after the wide spread of paper in those countries. A large number of bamboo slips have been excavated from the shipwreck since 2009 in Korea. Understanding the cause of deterioration of ancient bamboos is crucial f...

Microwave Modification of Bamboo Culm to Improve Permeability
2012 - IRG/WP 12-40592
Bamboo is a woody, valuable and strong material that has been used for a long time. In spite of its numerous beneficial properties, bamboo is susceptible to attack by fungus and insect therefore preservative treatment is regarded as necessary. Preservative treatment must provide sufficient uptake and even distribution in the culms for adequate protection. The treatability of dry bamboo, however, i...

Treating Bambusa vulgaris with neem seed oil against basidiomycetic biodegradation
2012 - IRG/WP 12-30608
Realising maximum benefits from bamboo stems/culms in Nigeria are presently constrained by their almost non-acceptance for applications in most structural and construction purposes, except in comparatively low quality and some temporary applications, such as scaffolding, owing to their susceptibility to easy destruction by agents of biodegradation as a result of their poor inherent natural durabil...

Decay resistance of wood treated with bio-friendly preservative systems
2016 - IRG/WP 16-30698
Due to more restrictive toxicological requirements and increased ecological awareness of consumers, wood preservatives containing biocides are no longer desired on the market. Therefore, research on new environmentally friendly formulations is of great importance. One of the possible solutions is to develop new preservatives based on natural substances, which are harmless to humans, animals and th...

The influence of log soaking temperature and thermal modification on the properties of birch veneers
2016 - IRG/WP 16-40749
In veneer manufacture the logs are routinely soaked in heated water baths in order to soften the wood prior to peeling. The temperature of the water may vary greatly between batches; however, the influence of log soaking temperature on veneer properties has had little research attention. Uncontrolled moisture is known to cause problems in wood-based materials, while thermal modification offers a m...
