Abstract:

In this article, the characteristics of the local marbles were determined by a series of experimental studies carried out on the samples taken from three different marble quarries in the Karahallı District of Uşak. The physical and mechanical properties of the samples determined in accordance with the standards evaluated together with their chemical, mineralogical and petrographic properties. Unit volume weight varies between 2.69 gr/cm3 and 2.74 gr/cm3 while water absorption values by weight at atmospheric pressure are between 0.27-0.35 % in Karahallı marbles. Uniaxial compressive strength values from the mechanical tests performed on Karahallı marbles are determined between 874.8 kg/cm2 and 1027.9 kg/cm2. Böhme abrasion resistance values are between 4.23 cm3/50 cm2 and 5.50 cm3/50 cm2. The CaO ratios of the marbles of the region are between 52.9-55.4%. The Uşak Green Marble contains a higher percentage of SiO2 (5.06%), TiO2 (0.16%) and Fe2O3 (1.25%) compared to other region marbles. The high SiO2 content of the Uşak Green Marble gives this marble a hard structure. It was determined that partial enrichment in TiO2 and Fe2O3 main oxide values in the compositions of opaque minerals, epidote and mica minerals gave this marble a light green color.
