Comparative investigations between thermal and microwave assisted digestion as a novel tool for the chemical analysis of inorganic wood preservative components
2011 - IRG/WP 11-20461
The correct chemical impregnation of wood requires an internal as well as external quality control of the treated wood. The active is located in a solid matrix, therefore it is often difficult to analyse such material since most analytical procedures are based on liquid systems. Because of this quite a number of methods – like extraction or thermal digestion - were developed in order to transfer...

Evaluation of timber bridges with special consideration of detail design
2017 - IRG/WP 17-40781
Since 1997 the use of wood in bridge construction has been increasingly criticized by the Hamburg federal state authority supposedly because of shortened service life due to decay. With regard to wood research, however, it is often suggested that use of timber is suitable for weathered structures as long as constructive protection measures will be observed. In order to unravel the reasons for the ...
