Study of micro-texture and skid resistance change of granite slabs during the polishing with the Aachen Polishing Machine

In this paper, massive granite slabs were cut from lumps of rock using a diamond saw. The surface of the stone slabs was then retreated so that the slabs were characterized by different degrees of roughness. On the other hand, the slabs had no macro-texture, so that the skid resistance depended exclusively on the micro-texture. The prepared slabs were polished under various polishing conditions using the Aachen Polishing Machine. Changes of the...
