| Summary: | The aim of this study is to investigate the effects of
different geothermal hot waters on some properties of Turkish red pine (P.
brutia Ten.) sapwood samples. The geothermal waters were taken from the
geothermal resources which are Kuzuluk, Geyve and Taraklı of Sakarya region in
Turkey. The treatment fluids with four different temperature (23ºC, 48ºC, 69ºC,
92ºC) were prepared (±2 degrees of precision) for each geothermal
resource. After the wood samples were
separately impregnated with these liquids using the thermic method, the
properties (rate of water absorption, modulus of elasticity, compression
strength parallel to grain) of these samples were tested. Findings obtained
from the tests were evaluated separately statistically for each properties. As a
result, while geothermal treatments did’t make a meaningful contribution to
modulus of elasticity of the red pine wood, they influenced the rate of water
absorption and compression strength parallel to grain properties significantly.
For rate of water absorption, the highest value (79.10%) was found in Kuzuluk
92°C treatmen but the least value (58.10%) was obtained in Geyve 48°C
treatment. For three different geothermal sources, it was seen that the
compression strength parallel to grain decreased significantly compared to the
control (untreated) samples.
