Abstract

Three-layer gypsum-bonded particleboards were prepared from oil palm stems and tested for their strength properties. Three wood:gypsum ratios (1:2.5, 1:3.0 and 1:3.5) were used and board density was varied between 1000 to 1300 kg m"3. The oil palm particles were not given any pretreatment and no chemical retarders were added in the wood:gypsum mixture. Boards with minimum density of 1150 kg TO3 and wood:gypsum ratios of 1:2.5 had strength properties which were comparable to those of commercial gypsum-bonded particleboards. The strength properties of gypsum-bonded particleboard were generally improved with the increase of density and gypsum to wood ratio. The highest MOR value (9.28 MPa) and internal bond (0.78 MPa) were obtained from gypsum-bonded particleboard manufactured at gypsum/wood ratio of 3.5:1 and density 1300 kg m.
