Grading the Performance of 18 Common Bamboo Species
2010 - IRG/WP 10-10723
A grading method for assessing the performance of 18 common bamboo species was introduced in this article. The method was based on 4 grade levels with corresponding scores of 4 reference indexes of bamboos including culm diameter, culm-wall thickness, natural durabiliy and preservative treatability. In comparison with the traditional utlilization of bamboo, the grading results showed that this gra...

Durability of heat treated Malaysian bamboo Gigantochloa scortechinii strips
2010 - IRG/WP 10-40514
Bamboo is one of the fastest growing plants and can be used for various products. In tropical countries such as Malaysia bamboo is abundantly available at reasonable prices, therefore it is used for numerous purposes. However, bamboo (as a lignocellulosic material) is susceptible to fungal and insect attack and it is difficult to protect by preservative treatment. Heat treatment is an option to im...

Chapter 4 - Propagation of bamboo
2007 - IRG/WP 07-10635-04
The cultivation and propagation of bamboos are very essential to
meet various human needs and environmental requirements.
Different methods of propagation and regeneration of bamboos have
been described in this chapter. The possibility of propagation
through seeds are restricted and limited because of its inadequacy
and non-viability. Due to this natural obstacle bamboos are
predominately pr...

Chapter 10 - Preservation of muli bamboo
2007 - IRG/WP 07-10635-10
Environmentally and economically very important mulibamboo
(Melocanna baccifera) grown in Bangladesh was fond to be easily
pressure treatable with CCA-C at green and air dry conditions. The
green and air-dried bamboo treated at same treating conditions and
concentration showed 110 per cent (2.10-times) higher retention in
air-dried bamboo than green one. Adequate lower retention

Chapter 11 - Preservation of talla bamboo
2007 - IRG/WP 07-10635-11
Researches revealed that the talla bamboo (Bambusa tulda Roxb.))
in Bangladesh could be full-cell pressure treated with CCA in green
and dry conditions. The dry bamboo gives higher loading
absorptions than green one when impregnated at same treating
conditions. Also higher absorptions are obtained at nodes rather
than internodes. Adequate penetration and retention results for
ground and wate...

Chapter 12 - Treatment Groups of Bamboo
2007 - IRG/WP 07-10635-12
Study on distribution of CCA in three major bamboo species in
Bangladesh, full-cell pressure treated at green and dry conditions
revealed two treatment groups and some treating principles. Higher
adequate treatment for ground and water contact use is only
possible by treating problematic bamboo species pre-kiln dried up to
half of its FSP and non-problematic species pre-dried up to FSP
(20% ...

Termite Resistance of Different Wood Panels Treated with Bifex® under Laboratory and Field Trials
2011 - IRG/WP 11-10745
The effects of Biflex® on termite resistance of laminated chip Board, MDF (Medium Density Fiber), Ply Wood and Veen Board at 50 ppm were evaluated. Laboratory and field trials resistance tests showed that all woods treated with Biflex were resistant to termites as compared to untreated ones. It was concluded that as chemical loadings increased, termite mortalities increased, and at the same time...

The resistance to Basidiomycetes fungi of chipboard 35 years after their industrial preservation with wood preservative on fluoroborate basis
2011 - IRG/WP 11-40546
The research on wood-based panels’ (WBP) behaviour towards fungi impact demonstrated rather low resistance of wood-based materials to wood rotting fungi. However, these materials are used in construction under conditions favourable to fungi growth. In such conditions WBP treated with wood preservatives should be used. Preservation durability is of great importance in such cases. The resistance o...

Preliminary laboratory bioassay to evaluate engineered Fibre-boards against subterranean termites C. acinaciformis (Isoptera: Rhinotermitidae)
2012 - IRG/WP 12-10768
In Australia, laboratory bioassays with subterranean termites typically contain groups of workers and soldiers in a substrate of moist mound material. This termite substrate may affect termite consumption, and the test materials create a favorable termite condition for the test. The main purpose of this test is to examine the effect of a melamine formaldehyde treatment of wood panels to evaluate t...

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...

Biological performance of wood- and bamboo-polypropylene composites: Effects of particle content, particle size and Zn borate
2012 - IRG/WP 12-40577
Particle content and size of wood material in wood plastic composites (WPCs) can affect efficacy of WPCs against fungi and termites. This study evaluated fungal and termite resistance of WPCs manufactured by using two different levels of particle content (50 and 70%) and three different particle sizes (30, 60, and 100 mesh). In fungal resistance tests, Tyromyces palustris, a standardized test fung...

Effects of Nano-Zycosil on Liquid and Gas Permeability of MDF
2012 - IRG/WP 12-40578
Effects were studied of zycosil nanoparticles, with size range from 30 to 90 nm, on liquid and gas permeability of medium density fiberboard. 100 g of nanozycosil was added to each kg of dry fibers. Density was kept constant at 0.67 g/cm3. The obtained results indicated that addition of zycosil to the mat resulted in a significant increase in gas permeability due to the lower fiber-content in the ...

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...

Observation of Boring Process of Larvae of the Bamboo Powder-post Beetle (Dinoderus minutus)
2014 - IRG/WP 14-10821
The bamboo powder-post beetle Dinoderus minutus is a major pest of felled bamboo in Japan. X-ray computer tomography (CT) was applied to non-destructively trace the movement of the larvae of this beetle inside the infested bamboo samples. The bamboo samples were prepared from pieces of the Japanese timber bamboo Phyllostachys bambusoides culms that were enclosed with adult D. minutus beetles for a...

Nano-Zycosil in MDF. Part I: Gas and Liquid Permeability
2014 - IRG/WP 14-40652
Effects were studied of zycosil nanoparticles, with size range from 20 to 80 nm, on liquid and gas permeability of medium density fiberboard. Nanozycosil was used at four consumption levels of 0, 50, 100, and 150 g/kg dry wood fibers. Density of all treatments was kept constant at 0.67 g/cm3. The obtained results indicated that the addition of zycosil to the mat resulted in a significant increase...
