Effect of Production Variables on the Properties of Cement Bonded Flake Board from Polyalthia longifolia (Sonn.)Thw. Wood
J.M. Owoyemi, I.O. Oyeleye
Abstract. The need to source for other woody materials for particle board like spent ornamental is on the increase due to reduction in the supply of timber from natural forest. Therefore, this study was aim at evaluating the effect of flake size and mixing ratio on the physical and mechanical properties of cement bonded particleboards produced from Polyalthia longifolia wood residues, a readily available and underutilized tree species. The production variables flake sizes of 19.85 mm, 19 mm and 6.35 mm and wood-cement ratios of 1:1, 2:1, and 3:1. The boards produced were subjected to physical properties tests such as water absorption, thickness swelling and linear expansion at 24, 48 and 72 hours. Water absorption, thickness swelling and linear expansion increased with decrease in flake size and mixing ratio. For the mechanical properties, the flake size of 19 mm had the highest strength as the mixing ratio increases while FS of 6.35 mm had the lowest strength. Flake size and mixing ratio had significant effects on the properties of the boards produced (P>0.5). Hence the study affirmed the suitability of spent Polyalthia longifolia flakes for Cement Bonded Board which can be used for both interior and exterior applications in building.
