The weathering on travertine in Döşemealtı(Antalya), Bucak(Burdur), Ermenek (Karaman) and the effects of the weathering on the engineering properties of the rocks

Due to the particular aesthetic appearance, tufa and travertine usage as surfacing stone greatly increased and they have become even more preferred. However, one of the most important problems for the porous rocks such as tufa and travertine is "weathering". So, the effects of weathering for this type of rock when used as construction materials (surfacing, landfill or riprap, etc.) have become a significant problem, too. In this study; effects of weathering in these rocks, when exposed to atmospheric conditions and saline environment in the coastal areas, to the engineering behavior of rocks have been investigated by laboratory experiments. The core samples were prepared from the rock blocks taken from three different locations; Döşemealtı (Antalya), Ermenek (Karaman) and Bucak (Burdur). Unit weight, porosity, water absorption ratios by weight and volume, uniaxial compressive strength, slake durability and P-wave velocities of the samples were determined. Then, after curing in NaCl, Na2SO4 and MgSO4 salts, the same parameters were determined again. As a result of comparison of the parameters; it has been shown that both atmospheric conditions and saline environment have adverse effects on engineering properties of tufa and travertine.
