Ecofriendly treatment to improving properties of beech wood

The objective of this study was to evaluate the effect of heat treatment on some conferred properties of beech wood namely durability,dimensional stability,elemental composition and color,allowing the heat treated wood to implement the exterior decoration of a building. beech boards were heat treated by conduction at 230°c for three times to achieve three mass losses due to thermo-degradation. the results showed a significant increase in the carbon content associated with a decrease of the oxygen content,a change of color,an improvement of the durability and enhancement of the dimensional stability of wood treated according to the intensity of treatment (duration). these results clearly indicated that the chemical modifications of wood cell wall polymers are directly responsible for these properties. all these modifications of wood properties were proportional to treatment intensity which is function to temperature and duration of treatment.
