ABSTRACT: Rubber wood asone of
light conctruction material was produced from community forest. The objective of theseresearch was to evaluatethe
physical and mechanical properties of tapping and untapping rubber wood for
considering as construction materials.physical and mechanical testing refers to
british standard (BS:373-1957). The result of these research showed that
physical properties value such as air dry moisture content, specivic gravity,
and longitudinal, radial, tangential shrinkage were 13,46-22,43%,
0,61-0,73,0,62-1,32%, 1,05-3,65% and 2,39-5,30%respectively for tapping rubber
wood. Furthermore forthe similar
patameter, untapping rubber wood were 7,44-14,68%, 0,57-0,71 and 0,6-2,09%,
1,27-4,13%, 2,5-5,35% respectively.The mechanical properties value included of
moe,mor, parallel compression strength, and hardness for tapping and untapping
rubber wood were 67813-129480 kg/cm2 and52759-107817 kg/cm2, 751,61-1071,68
kg/cm2 and 649-899,74 kg/cm2,
83,79-148,43 kg/cm2 and 80,54-137,88
kg/cm2, 16,99-21,94 kg/cm2 and 12,7-17,9 kg/cm2 respectively.
