dc.description.abstractPyroclastic rocks used in both historical and modern structures are inevitably exposed to various weathering processes, leading to damage and destruction of them. To reduce the effects of weathering caused by various atmospheric effects, geologists need to know what processes are more effective and how they affect rock bodies. In this study, our aim is to show the relationship between the weathering and welding degree of pyroclastic rocks, sampled around the Ancient City of Kilistra in Konya (Central Anatolia, Turkey). For this purpose, we conducted field trips, and used petrographic and laboratory techniques such as, physico-mechanical tests and accelerated weathering tests (i.e., Freeze-Thaw, F-T; Wetting-Drying, W-D and Salt Crystallization, SC). Pyroclastic rocks around Kilistra ancient city comprise two different sub-units: the unwelded, lower pyroclastic unit (LPU) and the welded, upper pyroclastic unit (UPU). Following cycles of F-T and SC tests, we observed an increase in porosity values, but a decrease in uniaxial compressive strength values, which was more evident in unwelded-LPU samples. Also, the significant macroscopic textural changes occurred in LPU samples, linked to their unwelded nature. However, physico-mechanical features of both LPU and UPU samples were not significantly changed after W-D tests. Altogether, our findings show that welding degree is one of the main factors controlling weathering and physico-mechanical properties of pyroclastic rocks, and also F-T and SC are more effective processes than W-D on weathering. Accordingly, our approach here could be used to protect the endangered historical structures carved into pyroclastic rocks around the world. (C) 2016 Elsevier Ltd. All rights reserved.en_US
