Preventive activity of geothermal resource waters against volumetric shrinkage and swelling properties of wooden

This study investigated the preventive effectiveness of geothermal resource waters on the volumetric shrinkage and swelling properties (working property) of wooden. For this purpose, Turkish red pine (Pinus brutia Ten.) wood samples were treated by immersion method with nine different geothermal source water from Turkey's three different geothermal fields (Afyonkarahisar, Denizli, Kütahya). A higher performance against shrinkage and swelling was observed in wood samples treated with Denizli’s geothermal resource waters. Also, all treated wood samples had lower swelling and shrinkage values compared to untreated ones. These reductions in swelling and shrinkage values show that geothermal resource waters could be effective in reducing the volumetric working property of wooden.
