Evaluation of the internal defaults and decay in old timber in building using non-destructive ground penetration radar (GPR) method
Volume 37, Issue 3 , September 2022, , Pages 217-228
Abstract
In this study, ground penetration radar (GPR) was used to assess the internal defects and decay of structural old timber in buildings and compare it with the sound wood. For this purpose, twelve samples of three wood species of beech, oak and yew with dimensions of 120 × 60 × 400 mm, and ... Read MoreEffect of steam treatment on chemical changes of wood components

Abstract
Poplar wood chips were treated by steaming in different conditions. The chemical composition changes of milled wood were studied. The obtained results indicate hemicelluloses degradation, reduction of acetyl groups and formation of organic acid during the treatment. It was also found that steam treatment ...
