ABSTRACT
Mechanical and Physical properties of Acacia Mangium for wood
cement board relation to particle size and cement
This research was performed to determine the properties of wood cement
board (WCB) made from Acacia mangium Wood.The different wood of
particle size (0.5mm,1.0mm and 2.0mm) and Wood cement ratio (1:25 and
1:30) was applied.The target of board density was 1300kg m3.The physical
(water absorption test and thickness swelling) and mechanical (bending test
and internal bending test) properties of the WCB were evaluated.From the
research, it showed that there is no significant different in physical and
mechanical properties of WeB except for internal bonding in different test
using the particle size.The result for modulus of rupture(MOR),water
absorption and thickness swelling meet the requirement standard of
MS544:2001.The application of different wood cement ratio also showed
same result pattern,where there is different no significant for all
testing.However wood cement ration 1:2.5 force feeds better (MOR) then
compared to 1:3.0.Higher content cement causes a general decrease in
MOR,WA and TS.
