Dimensional Stability, Thermal Degradation and Termite Resistant Studies of Chemically Treated Wood

Abstract

The efficacy of the preservative chemicals for the treatment of wood samples was evaluated in ground contact
against termite and fungus. The wood samples treated with boric acid followed by maleic anhydride, copper
acetate, sodium salt of diethyldithiocarbamate and kerosene showed higher dimensional stability efficiency in
terms of anti-shrink efficiency (ASE), bulk co-efficient (BC) and weight percent gain (WPG). The treated wood
samples showed higher strength properties such as modulus of rupture (MOR) and modulus of elasticity (MOE)
than the untreated sample. The treated samples could resist from termite and fungal attack and also extend the
service life.
