Standardization of CCA treated 45 hardwood species grown in Bangladesh for REB crossarms
1995 - IRG/WP 95-20059
Researches on 45 hardwood species grown in Bangladesh regarding density, moduli of rupture (MOR), colour and treatability of sapwood and heartwood, seasoning property and natural durability of heartwood revealed that both sapwood and heartwood of 17 species could be full cell pressure treated with CCA at impregnation pressure of 14-18 kg/cm² and only sapwood of rest 28 species could be pressure t...

Grading the Performance of 18 Common Bamboo Species
2010 - IRG/WP 10-10723
A grading method for assessing the performance of 18 common bamboo species was introduced in this article. The method was based on 4 grade levels with corresponding scores of 4 reference indexes of bamboos including culm diameter, culm-wall thickness, natural durabiliy and preservative treatability. In comparison with the traditional utlilization of bamboo, the grading results showed that this gra...

Grading UK Grown Larch for Durability
2013 - IRG/WP 13-10809
This paper reports on a joint study by BRE, the Forest Products Research Institute and TRADA Technology into the feasibility of grading UK grown larch to maximise its natural durability. The research was undertaken to assist sawmills and timber specifiers in the selection of larch timber suitable for external cladding. The findings indicate that the heartwood of larch has variable durability due t...

The assessment by visual grading, change of color and ergosterol content ratings, the resistance to mould fungi of treated with wood preservative Scots pine sapwood
2013 - IRG/WP 13-20514
The filamentous (mould) fungi belonging to Ascomycetes, Deuteromycetes group are an cosmopolitan organisms which attacks wooden elements disfiguring them, dropping their value and causing environmental and health hazard. The fungi in a short time cause mainly disfigurement of wood does not effect on strength properties of wood, but with strong prolongation of duration of conditions favourable for ...
