Abstract: The purpose of this study is to explore the effects of marble material properties on surface roughness and gloss. Therefore, four types of limestone are studied. The physical and mechanical properties of the samples were determined by laboratory measurement. Thin section analysis was used for mineralogical and petrological characterization. X-ray fluorescence (XRF) semi quantitative method was used for chemical analysis. Under fixed operating conditions, six different grinding and polishing tests were carried out on each marble unit using the same abrasive series. The relationship between material properties and surface quality was studied. Although the polishing and grinding tests were carried out under the same operating conditions, the roughness and gloss levels were differentobserved on different samples. Data obtained from the study proved that the main cause of this difference is textural and chemical composition variations of the marble specimen. Moreover, statistical evaluations showed that porosity, uniaxial compressive strength, and indirect tensile strength have strong effects on the surface roughness and glossiness of the marble specimen. The presence of an inverse relationship between the glossiness and roughness levels was determined as the result of this study as well.
