Volcanic tuff is widely used in Anatolian architecture and represents building stones of cultural heritage. The present study included a relevant assessment of the effect of four salt types and their four different concentrations on the durability of the Döğer tuff used as building stones of cultural heritages, which is subjected to salt crystallization tests. For this purpose, an investigation was conducted on their chemical, mineralogical-petrographical (polarized microscopy, XRD, SEM analyses, pore size distribution), and physical and mechanical properties as well as their deterioration behavior in the salt crystallization test by different salt solutions (and their different concentrations). In salt crystallization tests, sodium sulfate (Na2SO4·10H2O), magnesium sulfate (MgSO4·7H2O), sodium chloride (NaCl), and potassium chloride (KCI) solutions were used, and 2, 5, 10, and 14% concentration ratios were used for each salt solution. In this work, it was observed some physical and mechanical values decreased along with weight loss in samples. The ultrasound pulse velocity (UPV) and uniaxial compression strength (UCS) values of the Döğer tuff samples in all the salt solutions and concentrations decreased after the 15 test cycles. The tested Döğer tuff samples completely broke down in the 10% and 14% concentrations in the sodium sulfate, magnesium sulfate, and potassium chloride solutions.

不同盐溶液及其浓度比在盐结晶测试中对用作文化遗产建筑石料的Döğer凝灰岩(土耳其阿菲永卡拉希萨尔)的耐久性的作用

火山凝灰岩被广泛用于安纳托利亚建筑中,代表着具有文化遗产的建筑基石。本研究包括对四种盐类型及其四种不同浓度对用作文化遗产建筑石料的Döğer凝灰岩的耐久性的影响的相关评估,该凝灰岩已通过盐结晶测试。为此,对它们的化学,矿物岩石学(偏光显微镜,XRD,SEM分析,孔径分布),物理和机械性能以及在不同盐溶液的盐结晶测试中的劣化行为进行了研究(和它们的不同浓度)。在盐结晶试验中,硫酸钠(Na 2 SO 4 ·10H 2O),硫酸镁(MgSO 4 ·7H 2 O),氯化钠(NaCl)和氯化钾(KCI)溶液,每种盐溶液的浓度比率分别为2、5、10和14%。在这项工作中,观察到一些物理和机械值随着样品的重量减少而降低。15个测试循环后,所有盐溶液和浓度中的Döğer凝灰岩样品的超声脉冲速度(UPV)和单轴抗压强度(UCS)值均降低。经过测试的Döğer凝灰岩样品在硫酸钠,硫酸镁和氯化钾溶液中的浓度分别为10%和14%。
