Combined effects of thermal modification and ACQ-D impregnation on properties of southern yellow pine wood
2013 - IRG/WP 13-40637
In this study, samples of southern yellow pine sapwood were first thermally modified and then treated by the alkaline copper quat-type D (ACQ-D) wood preservative. Two heating temperature (180℃ and 220℃) and two concentrations of ACQ-D solution (0.9% and 1.35%) were used in the experiments. The combined effects of thermal modification and ACQ-D on leaching performance, mechanical prope...

Evaluation of color and gloss in decorative applied to cases of Pinus radiata wood impregnated (D. Don) copper type C azole micronized
2015 - IRG/WP 15-20571
Six treatments (one control and five decoration coatings) were applied to radiata pine wood treated with micronized copper azole (uCA-C), for outdoor use (R3) at a rate of 3.08 kg/m3 retention (T2). One decoration coating was applied before impregnation treatment: Prestain P (T3), and two, were applied in mixture with the uCA-C preservative Black Cylinder (T5) and Red Cylinder (T4). Two varnish we...

Decay resistance of beech wood and plywood treated with different type of phenol-formaldehyde (PF) resins
2016 - IRG/WP 16-40717
In this study treatment of beech and poplar wood veneers with (PF) resin industrial scale and screening tests of nine different phenol-formaldehyde (PF) resins were made. Specifically, the effect of different phenol-formaldehyde (PF) resin types on the resistance of beech wood against brown- and white-rot fungi was evaluated. Criteria for selection of optimal (PF) resin were based on minimum WPG ...

Development of Wooden Fireproof Structures for Mid- and High-rise Buildings in Japan
2021 - IRG/WP 21-30757
When constructing a mid-to-high-rise building more than 4 stories in general in Japan, it is necessary to have a fireproof structure stipulated by the Building Standard Law. The performance required as a fireproof structure in Japan is generally stricter than in other countries, and it is required to be structurally sound after a fire even without fire extinguishing activities. In order to satisfy...

Studies into the effect of soil type and soil layer on the in-ground decay of European beech
2022 - IRG/WP 22-20681
In this study, European beech (Fagus sylvatica L.) specimens were exposed to three different soil types; Podsol (Podzol), Braunerde (Cambisol), and Pararendzina (Regosol), in adapted terrestrial microcosm (TMC) tests according to CEN/TS 15083-2 (2005). Soils were sampled (250 mm deep) from field sites and separated into their constituent layers to deliver three TMC setups; mineral soil layer only ...
