Effects of superheated steam treatment on the physical and mechanical properties of light red meranti and kedondong wood.

Wood has been used as raw material for many applications due to its excellent properties such as good strength-to-weight ratio and aesthetic appearance. However, wood is susceptible to biodeterioration and dimensional instability because of its hygroscopic nature. The common practice to protect wood from wood-decaying organism is by applying chromated copper arsenate (CCA). Unfortunately, CCA is toxic and may leach out during its service life and impose serious threats to the environment and human (Lebow et al. 2008). Wood preservation methods without using harmful chemicals are prevalent in recent years. Increasing environmental awareness prompts the development of heat treatment in enhancing the properties of wood, especially dimensional stability and durability. Heat treatment, or thermal treatment, is an environmentally friendly approach where wood properties can be improved by the rearrangement of hemicelluloses, lignin and cellulose during the EFFECTS OF SUPERHEATED STEAM TREATMENT ON THE PHYSICAL AND MECHANICAL PROPERTIES OF LIGHT RED MERANTI AND KEDONDONG WOOD
