ABSTRACT
Interest
is growing everyday on proper utilization of wood waste resulting partly from
poor saw doctoring techniques and lack of skillful machinist for furniture
production and engineered wood products. The concept is to mitigate the
scarcity of wood raw materials supply. This study seeks to investigate the
properties of block-board as engineered wood product made from wood waste of Microbrelinia brazzavillensis, Brachystegia
eurycoma, and cedrus atlastica to
explore the viability of recovering of under desired dimension of wood for the
production of block-boards. The strips were processed and subjected to test to
determine the properties of the materials. The strips gotten from three
different wood species were used for the fabrication of four samples of
block-boards each. The sample specimens from the manufactured boards were
tested for both physical and mechanical properties. The test data were
subjected to analysis of variance (ANOVA), regression statistics analysis, and
pie chart and bar chart analysis in order to test for the level of significance
among the obtained parameters. Results showed the mean moisture content (MC) of
10.71%, 10.45%, 9.38%, and 10.86%. Water absorption mean value of 11.99%, 6.60%,
6.38%, and 6.65%. Density of 0.000659g/cm3, 0.000690g/cm3,
0.000715g/cm3, and 0.000662g/cm3. Comprehensive strength
value of 0.453N/mm2, 0.409N/mm2, 0.397N/mm2,
0.416N/mm2 static bending: MOE 1265N/mm2 and MOR 85.9
N/mm2 and impact test. Considering the contradictions about property
changes in wood, it was presumed that eventually alterations were of little
account and may be observed by the effects of other different samples. (i.e
difference in density). Therefore, standardized methods were preferred in the
study as they are proven to be reliable and allowing comparing the results of
recent literature values of wood.
