| Abstract: | In the present paper, an investigation was directed t owards the micro sructure detection of granite glossy surface at each separated stage ranging from sawing to grinding. SEM was employed to study the morphol ogies of the ground surfaces. A portable roughness instrument and a gloss meter were employed to analyze the roughness and glossiness of the ground surfaces r espectively. It is shown that although the black and red granites are very different in grain size, color, machinability and composit... |
