Studies on the fungicidal effectiveness of a petrol derived product as a creosote alternative
1986 - IRG/WP 3384
This work, appears first because of the necessity to find out a profitable use for a residual product of the petrol pyrolisis, and second, because the lack of high natural durability wood used until now-a-days to build posts and sleepers in creosote lacking countries. Our main objective was pointed to the characterization of this new product and to find out the effectiveness against the wood-destr...

Kinetic of the wood degradation produced by wood decay fung
1993 - IRG/WP 93-20016
The degradation degree of a wooden structure has a direct influence on its loss of mechanical strength. It's necessary to deepen in non destructive techniques which permit to extrapolate the results obtained in laboratory to structural timber used in the building's construction. This work studies the relationship existing between the pulse velocity of ultrasonic waves and the wei...

Biocontrol and bioprotection of wood decay and sapstain fungi
2003 - IRG/WP 03-10474
The most serious damages caused in the wood industries by decay and sapstain fungi, and the growing international pressures on the use of biocides products with toxic active ingredients harmful to human health and the environment, have made it necessary to search for alternative chemical products to protect the wood, and for the possibility to use micro-organisms as biological controllers. This la...

Damage by wood-attacking insects in buildings in Sao Paulo State - Brazil. (including errata slip)
1978 - IRG/WP 175
From 1974 to 1978 up to 602 buildings attacked by wood-boring insects were inspected by Instituto de Pesquisas Tecnologicas in Sao Paulo State - Brazil. Damage was caused mainly by subterranean termites, dry-wood termites and wood-attacking beetles. Up to US $ 1000,000 is the amount needed to control such insects in the buildings inspected...

Study of the degradation of retified wood through ultrasonic and gravimetric techniques
1994 - IRG/WP 94-40030
One of the non-polluting processes that increase the natural durability of wood is a thermal treatment in an atmosphere poor in oxygen, producing what is normally denominated "retified wood". In this study the validity of a non-destructive technique (ultrasound) in order to determine the biodegradation suffered by wood across time has been studied. For this reason, the behavior of a wood species (...

Wood decay of Pinus sylvestris L. by marine fungi
1990 - IRG/WP 1463
Waterlogged wood decay by marine microorganisms represents a major problem for the conservation of wood structures of historic value. It is important to know which kind of decay affects the wood from a conservation point of view. Enzyme activities of 14 marine fungi belonging to several localities were studied. Also, the weight loss and the rot type suffered by the wood at a microscopic level were...

Traitement des matériaux lignocellulosiques en présence des composés halogénés (Risques toxiques des produits de combustion)
1995 - IRG/WP 95-50040-17
From the point of view of the combustion products toxicity, the highest environmental hazard comes from the combustion of materials creating toxic products such as dioxins and dilbenzofurans. 95% of these are formed during incineration of different materials. The aromatics result essentially from the products of paper industry and from wood treatment. Formation of halogenated products during the c...

Situation of Wood Protection in Spain
2010 - IRG/WP 10-40511
This paper shows the actual situation of Spanish Wood Protection. In the evolution of this sector over the last years, three factors have been very important: the increase of the use of wood for both structural and decorative uses in construction, the development of the Technical Building Code, and the transposition and implantation of the Directive of Biocides to Spain in October 2002....

Environmental risk assessment of treated timber in service: The Environment Focus Group approach
2000 - IRG/WP 00-50162
In the context of the Biocidal Products Directive (98/8/EC), and of the OECD work on wood preservatives, the Environment Focus Group (EFG), comprising 8 institutes and the European Wood Preservative Manufacturers Group, has been working on the environmental risk assessment of treated timber in service. A literature review of emissions from treated timber has revealed that very little existing data...

Étude in vitro de la colonisation et de la dégradation structurale du bois d'aubier de Pin sylvestre par la Mérule: Serpula lacrymans Schum. ex Fr. S. F. Gray
1979 - IRG/WP 198
The degradation of Scots pine sapwood cell walls by Serpula lacrymans, a brown rot fungus, is observed after various periods of exposure from two weeks to twelve weeks. The observation by microscopy shows that the hyphae of Serpula rapidly invade the wood tissues as cell wall degradation starts. That deterioration is not gradual, it is observed to be very irregular as well within the whole of the ...
