Chapter 7 - Treatment processes of bamboo
2010 - IRG/WP 07-10635-07
For adequate penetration and retention of preservatives in woody
bamboos at green, dry, solid and sliced conditions different possible
and applied treatment processes have been described along with
their classifications. The treated bamboo can be used as building
materials; the sufficient treatability ensures its long-term best
utilization at ground contact and indoor. All the processes descr...

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% ...

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...

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...

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...

Influence of selected additives on organic fungicides for control of bamboo mold fungi
2013 - IRG/WP 13-30626
In order to assess the long-term efficacy of supplemented organic fungicides in outdoor applications, additives - including the antioxidant butylated hydroxytoluene (BHT) and a UV absorber and free radical scavenger benzotriazole (BTA), were selected to mix with the fungicides propiconazole or tebuconazole. Freshly cut samples from four-year old bamboo stems were treated with combinations of the c...

Bamboo: A poor man’s timber
2015 - IRG/WP 15-10852
Bamboo, known as poor man’s timber in the past gained some importance in the last decade when TIFAC under Department of Science & Technology and Ministry of Agriculture awoke to find a better future for this unique gift of nature. Until then it was considered a good for nothing grass suitable only for making paper and building effigies of Ravan, Kumbhkaran and Meghnath year after year at Dussehr...

Performance of kiln-dried and air-dried anti-sapstain treated pallet timber under use scenarios against wood discolouring fungi
2015 - IRG/WP 30669
During their lifespan there is a high probability that wooden pallets and packaging material will be exposed to rainfall or rewetting conditions, increasing the risk of growth of discolouring fungi. Kiln-drying of wooden pallets and packaging material without anti-sapstain treatment does not give efficient protection against wood discolouring fungi during rewetting periods. However additional temp...

Facile in-situ growth of Ag-TiO2 nanoparticles on polydopamine modified bamboo with excellent mildew-proofing
2019 - IRG/WP 19-30734
Bamboo with good mechanical properties, fast growth rate and low growth cost is one of very utilitarian structural material from forest resources only less important than wood. But it is especially easy to mildew during outdoor service resulting in appearance mould scattering and corrosion. In this work, a facile method was developed to increased mildew-proofinging capability of bamboo. Mussel-ins...

Chemical composition and performances of slow pyrolysis by-product from sugarcane bagasse for wood protection
2020 - IRG/WP 20-30752
Pyrolysis distillate or bio-oil, a by-product of biomasses’ slow pyrolysis in the char-making process, has been traditionally used as bio-pesticides by Asian farmers. Due to its large composition of bio-active chemicals, bio-oil obtained from various biomass has become of interest in many applications, including wood protectants. This study aims to characterize the chemical composition of bio-oi...
