Effects of geothermal hot water treatment on rate of water absorption, modulus of elasticity, compressive strength parallel to grain of Brutian pine wood

Abstract

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.
