IRG soft-rot stake test - Site 03 Australia. Progress Report No. 3
1982 - IRG/WP 3202
The performance of test stakes was examined after four (4) years. Hardwood stakes treated with CCA showed significant soft-rot attack. The exception to this was Alstonia scholaris which was similar in performance to Pinus sylvestris. A supplementary test containing stakes treated with CBC, PCP and creosote, showed attack in all hardwoods examined. Little decay was found in stakes of Pinus sylvestr...

300 years water-logged wood: Treatability with CCA-C
1998 - IRG/WP 98-40103
The treatability of 300 years water-logged and recent wood (Abies bornmülleriana M.) was assessed by dip treatment and vacuum and pressure cycling with CCA-C. Treatment runs were evaluated on the basis of weight gain retention and radial and tangential penetration measurements. The preservative penetration and retention levels in the 300 years water-logged wood were higher than in the recent wood...

Triazoles: Synergism between propiconazole and tebuconazole
1995 - IRG/WP 95-30092
The synergistic action of the two triazoles propiconazole and tebuconazole against wood rotting fungi can clearly be demonstrated by determination of toxic values according to Standard EN 113. The results show that by combining both triazoles a better balanced spectrum of activity can be achieved. The reduction of the toxic values against the white rot fungus Coriolus versicolor (toxic values of t...

Bending properties of treated western hemlock plywood
1996 - IRG/WP 96-40064
This study investigated the mechanical properties of western hemlock plywood after treatment with waterborne preservatives and redrying. Unlike previously reported results for southern pine plywood, western hemlock plywood was more sensitive to redrying temperature than to preservative treatment. Generally, western hemlock plywood was affected by temperature and other variables. Losses in mechanic...

Review of remediation methods of sites contaminated by wood preservatives - testing of filter material for use in permeable barrier technology
1999 - IRG/WP 99-50141
Several treatment methods are currently available for treatment of contaminated sites. Soil and water can be treated by immobilisation, separation or destruction of contaminants. It has been common to use intensive treatment methods starting with soil excavation to reach strict purification goals. However, technical and financial reasons make it difficult to reach the desired treatment criteria. A...

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 4: Report of second inspection (12 months) in Australia
1979 - IRG/WP 448
Previous reports have presented full details of the treatment and installation of the test specimens in Sydney Harbour during December, 1977, and of the results of the first (6 months) inspection made during June, 1978. At the June inspection it was apparent that the plastic tubing used to make up the frames from which to suspend the specimens was inadequate for the job and not strong enough to su...

A new accelerated field test for termites

Isolation and identification of bacteria from CCA-treated eucalypt power transmission poles
1987 - IRG/WP 1317
Bacteria have been isolated from CCA treated Eucalyptus maculata poles which possessed characteristic bacterial decay patterns. Cultures were isolated on a number of different media which had been inoculated with a splinter of degraded wood. Primary tests indicated that most isolates belonged to the genera Pseudomonas and Bacillus. The species Pseudomonas cepacia was most frequently isolated....

Leaching of CCA preservative from treated timber in marine environment
2001 - IRG/WP 01-30254
Knowledge on the amount of preservatives leaching out of treated wood is essential to optimise the chemical loading in various species of timber required for different end uses. In order to gain more insight into this aspect, the residual CCA content in 40 treated timber panels belonging to 14 species removed on destruction by marine organisms from a series of durability tests conducted in Kochi w...

Volumes and weights of different CCA-C treated wood poles, anchor logs and crossarms of REB at air dry condition
1996 - IRG/WP 96-40073
Researches revealed the unit volumes and weights at air-dry condition (12% MC) of different poles, anchor logs and crossarms species of REB from this world. The softwood products are lighter than hardwood products. Inversely the unit volumes of softwood poles are higher than those of hardwood poles. Red pine (Pinus resinosa), radiata pine (Pinus radiata), blue pine (Pinus wallichiana), fir (Abies ...

Copper-resistant fungi on pressure impregnated wood in Denmark
1994 - IRG/WP 94-10078
The occurence of Amorphotheca resinae Parbery and its asexual stage Cladosporium resinae (Lindau) de Vries on CCA and CCB treated wood has previously been shown. In the autumn 1993 some other blue stain fungi were found on CCP and CCB treated pine timber, such as Ophiostoma minus (Hedgc.) H. and P. Sydow, Ophiostoma pilifera (Fr.) H. and P. Sydow and Ophiostona piceae (Munch) H. and P. Sydow. The ...

Leaching of CCA components from treated wood under acidic conditions
1993 - IRG/WP 93-50004
The leaching of CCA components from treated wood under acidic conditions were investigated. Western hemlock treated with three types of CCA and two levels of target retention was subjected to leaching at four different levels of pH. After leaching tests, leached samples were subjected to laboratory decay and soft rot tests. The amount of CCA components leached was dependent on acidity of leaching ...
