3、 October 2009.INTRODUCTIONDimension stone, as used here, is natural stone that has been selected and fabricated to specific sizesor shapes, with or without one or more mechanically dressed or finished surfaces, for use as buildingfacing, curbing, paving stone, monuments and memorials, and various in
4、dustrial products. The termdimension stone is in contradistinction to crushed and broken stone, such as is used for aggregate,roadstone, fill, or chemical raw materials. Because all stone is a natural material, the definitionexcludes all manmade materials that simulate stone. In common practice, som

This sectiondescribes common finishes and classifies them into a number offamilies by relief or roughness. The finishes
44、 in each family arealso arranged from the least relief to the most relief.Stone finishes are a complex matter for a number of reasons.New manufacturing or finishing methods or variations orcombinations of other methods of finishing stone are continu-ally being developed. Stone finish names sometimes
45、 overlap orare variations of other finishes.Finish options for any kind of stone vary by the geologiccategory of the stone (whether igneous, metamorphic, orsedimentary) and the unique combination of geological orphysical properties of the stone type. This means that anyparticular finish cannot be pu
46、t on every type of stone (seeApplicability of Finishes for Various Stone Types Table inGuide C1528 for Selection of Dimension Stone for ExteriorUse). The individual definitions are sometimes nonspecific ornearly overlap. In practice, a detailed definition of a specificstone finish is established bet
47、ween the producer and designerthrough dialogue, or reference sample(s), or both.The family or individual title “finish” will be used uniformlythroughout this section for ease of reference, although the term“surface” would be more accurate when no work has been doneon it and no improvements made post
48、quarry (as in certainrough finishes; see Note 2). “Surface” will be used uniformlyin the sense of the outward appearance or face of the stone.FIG. 1 RusticationC119 0813Thus we have the Least Textured Finishes (family) and thePolished (finish)a highly-reflective surface, and so forth.Surface Variati
