Properties Of Block Boards Made From Wood Wastes Of Microbrelinia Brazzavillensis, Brachystegia Eurycoma, And Cedrus Atlanstica In Cross River State, Nigeria:- Ushie Emmanuel O
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 ot
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,
0.397N7mm2, 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 ofrecent
literature values of wood. Keywords; Wood, block-boards, wood strips.
