Publisher: | Baski | Abstract: | In this study, the minero-petrographical, chemical properties as well as basic physical and mechanical properties of the travertine samples, known as Afyon Silver from Emirda? (Afyonkarahisar) region were comprehensively examined. The travertine samples have completely crystalline texture and consist of carbonate minerals (calcite in composition) with ranging from 100-250 ?m. XRD and Confocal Raman Spectrometer studies are supported these results. The average CaO content of the travertine samples were 55.75%, MgO content <0.012%, Fe2O3 (as total iron) content 0.020% and MnO content 0.101%. According to the results of the physico-mechanical test, the apparent dry density values were between 2.38 and 2.52 g/cm3 and the saturated density values were between 2.43 and 2.55 g/cm3. Open porosity and water absorption values were determined as 5.24% and 1.21% to 2.19%, respectively. The vertical abrasion values of the travertine samples were between 22.99 and 28.13 mm, and the average value was 25.91 mm. Sonic velocity values were measured between 4.49 and 5.87 km/s. The uniaxial compressive strength was determined between 23.17 and 53.22 MPa. In addition, 3 and 4 point bending strength tests were performed on the plate samples and the mean values were determined as 14.67 and 11.19 MPa, respectively. According to the freeze-thaw test results, the average loss of material by weight was 0.86% and there is a negligible amount of differences in uniaxial compressive strength. As a result of mineralogical, petrographic, chemical and physico-mechanical tests, It is determined that travertine samples have the characteristics that can be used as natural building stones.
