Wood preservative development: Have we learnt anything, and where will it take us?
1994 - IRG/WP 94-30054
This paper addresses the disparate approaches to the development and approval of wood preservatives used in a number of regions, and the implications of the test requirements, or lack thereof, on the likely performance of the subsequent treated wood in service. The test methodologies and performance criteria used in various regions will have long term consequences for the future of the wood preser...

Comparative environmental impact analysis of telecommunication utility poles: Treated wood and fibreglass
1999 - IRG/WP 99-50136
This study is aimed at providing the information necessary to assess the main environmental implications of different materials utilised in construction of utility poles. The study was performed on fibreglass and CCA treated poles timber. The work has been carried out by identifying and quantifying energy and materials used and wasted released during the entire life of the pole. The interactions w...

Evaluating the potential of modified wood for use in marine environments using a short-term laboratory bioassay
2004 - IRG/WP 04-10525
Chemically modified wood may be an alternative to preservative treated timber for marine structures. In this study a screening laboratory test using the wood-boring isopod crustacean Limnoria quadripunctata was used to assess the durability of chemically modified Pinus sylvestris, Pinus radiata and Picea sp. Most of the treatments used a combination of one of two of types of the resin dimethyloldi...

Information from the COIPM Wood Group
1986 - IRG/WP 4130
The Chairman outlined the progress of the co-operative work "testing the resistance to marine borers of heat shrinkable polyolefin sheathings and of wood treated by vacuum/pressure with polymers (polystyrene)". The first part of the work has been started: the samples of wood wrapped with shrinkable polyolefin sheathings have been prepared and sent to the stations participating. The second part of ...

Utilization of plasma treatments in the field of wood protection
2021 - IRG/WP 21-40912
Plasma treatments have been used for modification of surfaces of wood and wood-based materials for some decades and solutions were developed to apply it for wood protection. This contribution aims to present the background, introduce the available plasma technology, and to give an overview on the typical applications and benefits....

An evaluation on durability of untreated mining timber support
1997 - IRG/WP 97-20121
Wedge blocks in dimension of 5 x 7 to 8 x 155 cm3 were cut from indigeneous scots pine pitprops. Each of wedge block pairs were numbered and half of them were placed as the test blocks between the steel arches and the strata in a hard coal pit. Controls in laboratory and test wedge blocks in the mine were then sawn into 20 by 20 by 300 mm standard test sticks. Impact bending, static bending and MO...

Soft rot decay of Eucalyptus maculata Hook. in different soils from Queensland, Australia
1980 - IRG/WP 1113
In the present work, different Queensland soils were chosen and their gross effects on the decay of treated and untreated Eucalyptus maculata examined. The soils were also amended with various levels of phosphate to study the response of the wood decay mycota to an increasing supply of this nutrient. Phosphate amendment was chosen because of the wide-scale use of superphosphate on Queensland soils...

In service performance of wood sound abatement barriers
2024 - IRG/WP 24-41006
Sound abatement barriers made form treated hem-fir in service near Vancouver, Canada were inspected after about 10-12 years in service. The barriers appeared in good condition and no boards were to the point of needing replacement. The sound abatement decibel readings at all locations indicate they perform as well as concrete barriers and exceed the 5 dBA regulatory requirement for noise reduction...

Chromium on the surface of CCA-treated wood
1978 - IRG/WP 386
Chromium in solutions of CCA preservatives is predominantly in the hexavalent state (Cr VI). It is well known that Cr VI is associated with dermatitis and skin ulceration in workers handling chromium containing products and processes. When reduced to the trivalent state, however, chromium is considerably safer. An essential part, therefore, of safety procedures in any chromium - using industry is ...

Comparisons of differences in electrical conductivity and corrosivity between CCA-oxide and CCA-salt treated wood
1981 - IRG/WP 3178
CCA preservatives have served well in many applications throughout the world. In developed areas it is the preservative in demand for clean dry paintable surfaces with long durability. In developing areas it is widely used for economic and logistical reasons. With the current emphasis on energy resources, the CCA preservatives are gaining greater acceptance as a substitute for hydrocarbon-related ...

Examination of the Pilodyn as a non-destructive test method for detecting decay in CCA treated eucalypt poles
1982 - IRG/WP 2177
Below groundline condition of 274 CCA treated eucalypt poles comprising 13 different species was examined using 6 and 12 Joule Pilodyn units with 2 and 2.5 mm diameter pins. The data obtained was used to calculate regressions of density on pin penetration. A decrease in density was accompanied by an increase in pin penetration. The best correlation was found using the 6 Joule, 60 x 2.5 mm² diamet...

Soft rot fungi as possible sources of odor in impregnated wood in buildings
1993 - IRG/WP 93-20013
Wood preservatives are frequently used inside houses. In several cases impregnated wood, particularly when used in crawlspaces or other near-ground constructions, has been found to be a source of odor. Mold fungi, soft rot fungi actinomycetes or bacteria growing on impregnated wood are possible producers of the odor. Analyses of volatile emissions from impregnated wood with odor and pure cultures ...

Blue stain resistance of exterior wood coatings as a function of their typology
1998 - IRG/WP 98-20145
Paints and wood stains were evaluated on their blue stain resistance using both EN 152 method and the reverse method. The typology of these exterior coatings was varied including standard and high solid solvent-borne coatings as well as different types of waterborne coatings. For the water-borne acrylic, alkyd based and hybrid coatings both applied as opaque primer paints and as decorative wood st...

The volatilization of arsenic on burning copper-chrome-arsenic (CCA) treated wood
1978 - IRG/WP 3111
Small scale burning experiments are described involving copper-chrome-arsenic treated wood. Approximately 20 per cent of the arsenic was volatilised when the wood was burned in air but 60 per cent when burned in an oxygen-enriched atmosphere, this increase is attributed to an increase in combustion temperature. Although a small increase in arsenic evolution was found with an increased concentratio...

Balance of arsenic and recycling
2002 - IRG/WP 02-50189
Instead of importing considerable quantities of arsenic to Europe, it would be sensible to utilize the arsenic recovered in the recycling process in the manufacture of CCA-wood, in the metallurgical industry as well as in other ways. When copper is also processed into a form easy to
utilize, it may be possible to utilize chrome as well. When these developments are implemented, it can be said th...
