| Summary: | Properties of acacia mangium wcb in relation to
particle size and additives (Na2Sj03)
Particle size and Cldditives (Na:,S,O;) had significance effect on physical
and mechanical properties of WCB. One WCly analysis of variance
(ANOVA) hCls been used to examine if there is any significance
differences between the populations mean. The findings were revolved
around the mechanical and physical properties of Wood Cement Board
(WCB) from ACClcia mangium. The two parameters that involved in this
study are the particle sizes and the additives (Na2S,OJ) Particle size,
additives (Na;,S,OJ and the correlation between particle size and
additives (Na..S,O.l) influence on all the WCB properties. The values of
physical properties for particle size effect all met the standards of
MS544:2001 except for particle size 2.0rnm of 0% Na2S,03 and 15%
Na2S,O" which are WA not met the standards of MS544:2001. Effect of
particle size on mechanical properties indicate fluctuation due to the
decreasing of particle sizes while the effect of particle size on physical
properties also show fluctuation due to the decreasing of particle sizes.
Meanwhile,the effect of additives which are 3% of Na2S,03 tends to
cause higher values of MOR (136MPa), MOE (5,979MPa) and IB
(1.56Mpa) on the effect of mechanical properties. The effect of additives
(Na2S,OJ) on physical properties, the value of WA and TS tends to
decrease corresponding due to the percentage (3%) of Na2S,OJ. |
