Eucalyptus, an evergreen tall tree native to Australian and Tasmania, has been
famously utilized in many industries in Thailand. This is because of their plasticity and
their capacity of rapid growth. This study involved the study of physical and mechanical
properties of Eucalyptus wood for its use in construction. The test specimens were taken
from Eucalyptus wood of age 3 and 5 years planned in the eastern provinces of
Thailand, Chonburi, Rayong, Chachoengsao, Chantaburi, Trat. Three basic properties tests
of specific gravity, moisture content, absorption, were carried on according to ASTM
D2395-02. In addition, five mechanical properties of Eucalyptus wood named as
compression parallel to grain, compression perpendicular to grain, shear parallel to grain,
tension, and cleavage, were tested according to ASTM D143-94. Decreasing the moisture
content, the study presented an increase in all five mechanical properties. Oppositely,
all five mechanical properties increased with the wood of advanced years. Moreover,
the location of sample woods from the wood log yielded in significant discrepancy of
mechanical properties and failures. |
