Penetration analysis of two common bamboo species - borak and jawa of Bangladesh
2002 - IRG/WP 02-40247
Preservative treatment of two bamboo species, namely borak (Bambusa balcooa Roxb.) and jawa (Bambusa salarkhanii Alam) was carried out with chromated copper boron (CCB) preservative by dipping method. The variation in preservative penetration between the two different species was determined. It was found that preservative penetrates into borak quicker than into jawa and easier into air-dried bambo...

Comparative study on physical properties of four fast growing timber species of Bangladesh
2006 - IRG/WP 06-10570
Ghoraneem (Melia azedarach), Rain tree (Albizia saman), Sissoo (Dalbergia sissoo Roxb.) and Akashmoni (Acacia auriculiformis) plantations are started as a fast growing timber specie from a few years back in Bangladesh. Initian objectives were to get fuel wood only from those trees, but a very positive response was found for Ghoraneem, Rain Tree, Sissoo and Akashmoni timber in the users market by c...

Present status and potentiality of the economic utilization of the sawmill residue and wastage in Bangladesh
2004 - IRG/WP 04-50211
This study has been carried out to obtain a clear picture about the current status of utilization of sawmill residue and wastage. In order to accomplish the study a random survey has been conducted in 27 sawmills of Khulna District and in 10 sawmills of Jessore District. Most of sawmills in these area run at a very primitive level compared to modern technology. Species used for conversion mainly d...

Preservative treatment of two bamboo species Borak (Bambusa balcooa Roxb) and Talla (Bambusa tulda Roxb) by Boucherie method
2003 - IRG/WP 03-40262
Bamboo is widely used as a construction material in rural and urban areas of Bangladesh. It is perishable in nature and highly susceptible to the attack of borer, termites and fungi. As a result, bamboo products do not last long. This short life of bamboo is increasing demand thereby increasing pressure on our homestead and natural reserve of bamboo. For this reason, it is needed to make the bambo...

Present status of using treated wood and private house owner’s expectations in Bangladesh
2004 - IRG/WP 04-30329
In a developing country like Bangladesh more than 80 % of the total population lives in rural areas where building materials are mainly comprised of wood, bamboo, thatch grass, golpata, etc. All these materials, being cellulosic, are easily infected by deteriorating agencies like fungi, termites, beetles etc., as climatic condition of the country is ideal for their thrive. This is a great wastage ...

Study on Tanalith E treatability of rubberwood (Hevea brasiliensis) grown in Bangladesh
2006 - IRG/WP 06-40337
Rubberwood (Hevea brasiliensis) is very important but it is susceptible to various wood degrading agents. To ensure the effective protection of rubberwood, arsenic free Tanalith-E (An AWPA CBA-A: Copper Azole- Type A composing Copper, Boron and Tebuconazole) preservative has been used through dipping process. It is found that the penetration of copper and boron in rubberwood is more distinctive an...

Comparative study between full cell and passive impregnation method of wood preservation for laser incised Douglas-fir lumber
2007 - IRG/WP 07-40359
Many wood species are highly resistant to conventional pressure treatment. To improve the chemical impregnation into Douglas-fir (Pseudotsuga menziesii Franco) lumber, the passive impregnation method had been developed. In this study, ability of the passive impregnation for lumber was compared with a conventional full cell method. Square Douglas-fir lumber with the incising density of 10,000 holes...
