Abstract
Many factors including depletion of the forest, environmental awareness, and
generation of large quantities of agro-forest residues have increased the need
to partially or wholly replace wood with agro-forest residue for particleboard
production. This study assessed the decay resistance of particleboards pro duced from four agro-forest residues using cassava starch and urea formal dehyde as adhesives. Musa paradisiaca pseudostem, Theobroma cacao stem
and pod, and sawdust of Ceiba pentandra were used for the study. Properties
determined were: Weight loss, decay resistance rating and decay susceptibility
index. These properties were evaluated after 12 weeks of exposure to Cori olopsis polyzona in accordance with ASTM D 2017-05. The results indicate
that the weight loss for Musa paradisiaca pseudostem particleboard was least
for both urea formaldehyde and cassava starch adhesives. Even though almost
all the particleboards produced were classified as resistant or highly resistant
to fungi attack, those produced with urea formaldehyde had better decay re sistance properties than that of cassava starch. Furthermore, particleboards
coated with synthetic polyvinyl lacquer had better resistance to fungi attack
than the uncoated ones. At 5% level of significance, the agro-forest residue,
adhesive and surface finish as well as their interactions had significant effects
on decay resistance of the particleboards produced. It is recommended that
further studies which aim at determining the effect of combination of the
agro-forest residues and that of urea formaldehyde and cassava starch be
conducted to determine their effects on decay properties of particleboards.
