A novel method for delivering fluids into bolted wooden components.
2004 - IRG/WP 04-40280
The paper describes the development of a washer that enables fluids such as wood preservatives and adhesive resins to be delivered to bolted wooden components in-situ. The system was developed to meet the criteria of low cost and the ability to tolerate inaccurate drilling of holes in the wooden members....

A novel device for detecting internal defects in wooden poles
1989 - IRG/WP 2329
The diagnosis of internal defects caused by termites and decay in hardwood transmission poles has been investigated using a novel Automatic Feed Drill (AFD) pole testing device. Internal defects were recognised by changes in drill feed-rate as the automatic air-driven drill traversed its 100 mm working stroke. The instrument is portable, simple to operate and recognises defects instantaneously. Te...

Studies on the preservative treatment of round bamboos by a new technique
1989 - IRG/WP 3536
Nature has offered a versatile and cheap material bamboo, which is generally found to grow principally in forest areas from sea level to about 400 m wherever suitable combination of ecological factors prevail. This potential renewable natural resource has been since times immemorial, exploited by mankind for a variety of purposes specially in developing countries like Asia, Africa and South Americ...

The influence of drilling patterns on the distribution of toxicants from Polesaver Rods in hardwood poles
1994 - IRG/WP 94-30051
Polesaver Rods are solid rods of wood preservative that are used as a groundline maintenance treatment to control biodeterioration in hardwood transmission poles in Australia. The rods are inserted in holes that are drilled in a prescribed manner to distribute the toxicants into the critical groundline region of the poles. To determine the influence of drilling patterns on the distribution of toxi...

Preservative treatment of round bamboos by a new technique - Some further studies. Part 1
1990 - IRG/WP 3607
In general, the easy susceptibility of bamboos to wood destroying agencies is a major constraint in its rational utilisation. This is more so in tropical countries like India where wood destroying agencies are quite active. In an earlier publication, it was reported that round bamboo specimens of Bambusa balcooa, having three nodes, could be satisfactorily treated by CCA by a new technique develop...

Brief introduction of a research project on the wood materials from an ancient Byzantine port unearthed during drilling for underground rail tunnel in Istanbul
2008 - IRG/WP 08-10641
A research project has been recently started to evaluate some properties of wooden materials from the biggest port of ancient times called Port of Theodosius I in Istanbul, Turkey. The ruins of the ancient Byzantine port during the excavations were recently uncovered in the Yenikapi site where an underground rail tunnel construction has been in progress in Istanbul. The wooden objects unearthed fr...

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...

Quasi-in-situ durability tests on oak timber bridges
2013 - IRG/WP 13-20510
This study aims on developing a method for determination of wood durability on samples taken from real structures in service. Therefore quasi-in-situ durability tests have been conducted exemplarily on timber bridges made from English oak (Quercus robur L.). Drilling cores were found to be a feasible alternative to standard specimens for laboratory durability tests against pure cultures of Basidio...
