Tests on the effectiveness of concentrated borate wood preservative
2009 - IRG/WP 09-30500
Tests were carried out to examine the toxicity of concentrated borate wood preservative to termites, fungi and mammals. The results showed that the preservative treated timber had high resistance to termite or decay and its acute oral toxicity belonged to low grade. The research shows that concentrated borate solution is an environmentally sound preservative and can be used in non-pressure treatin...

The natural durability and preservative treatability of 11 bamboo species
2010 - IRG/WP 10-10708
Tests on the natural durability and preservative treatability of 11 common bamboo species were conducted. The results showed that there was a linear relation between bamboo density and its preservative retention by mass, and the preservative retention of bamboo reduced while its density increased. The test also showed that there were significant differences in the natural durability of bamboos, bu...

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...
