Proposals for collaborative work on laboratory soft rot testing
1986 - IRG/WP 2265
Proposals for collaborative experiments based on soil burial are presented. It is intended to study the use of defined horticultural loams with a view to obtaining more reproducability in laboratory soft rot tests....

Final proposals for collaborative work on laboratory soft rot testing
1987 - IRG/WP 2292
In this paper proposals are made to scope, timbers, preservatives, leaching, drying, soil type, moisture content, soil burial (blocks and stakes), incubation and dry weight determination and the expression of results....

Effect of soil type and moisture content on soft rot testin
1986 - IRG/WP 2270
Several soils of different types were tested at a range of moisture contents for their suitability for use in a soil burial soft rot test. Their effectiveness was assessed by weight loss in CCA treated and untreated beech and birch outerwood. A horticultural loam (John Innes No. 2) was the most appropriare soil in terms of amount of weight loss caused, tolerance to changes in soil moisture content...

Liquefied wood polyols: Ecofriendly bio-based preservative for sustainable protection of wood from Termite attack
2018 - IRG/WP 18-10916
The major problems encountered in both indoor and outdoor utilization of wood are biological decay due to termite. The modification of wood with liquefied wood polyols has been found to be effective against termite attack. The liquefaction of wood aims to utilize woody wastes which are being generated during primary and secondary processing of wood in wood based industry. One of promising approach...

Novel approaches for improvement of dimensional, photo- and thermal stability of wood through liquefied wood polyols impregnation
2019 - IRG/WP 19-40884
The major problems encountered in both indoor and outdoor utilization of wood are due photo instability and dimensional instability. The modification of Melia dubia wood for ultraviolet resistance and dimensional stability with liquefied wood has been carried out through impregnation method under solvent free conditions. The level of impregnation in modified wood was estimated by weight perc...

Comparative study on the efficacy of biobased wood preservative over conventional wood preservatives against fungi and termites
2022 - IRG/WP 22-30761
The current focus of wood preservation research is on developing wood preservatives from natural and environmentally compatible compounds for industrial application. Liquefaction of wood is one of the promising approaches to utilize woody waste where the wood powder is converted into a chemically active liquid with the help of a liquefying agent like phenol, cresol, plant-based solvent as CNSL and...
