Abstract The physico-chemical analysis of bark-free oil palm trunk (OPT) in comparison with rice husk (RH) was evaluated for their suitability in building construction. The results showed insignificant differences in both chemical and proximate analysis of the two fillers. The optimum value for flexural and nail-pull hardness test was at 20% OPT loading. The OPT mixed gypsum composite shows good thermal stability suitable to be used as a new type of filler for the reinforcement of gypsum composite. The limitation however is its hygroscopic properties that might affects the dimensional stability of gypsum composite when contact with water.
