1. Introduction. The stone-masons often use the term marble to any rock which can be easily polished [21].Limestone, schist, travertine or even granite can be considered as marble in the business world [23].Marble technically can be described as a metamorphic rock that consists predominantly of calcite and/or dolomite [14].Marble …
Granite dust is a non-plastic material that exhibits high shear strength with zero carbon emissions. The fine state of stone dust results in a large specific surface area. The physical properties, chemical composition, and mineralogy of stone dust vary with the type of parent rock, but is consistent with the quarry at site .
The elemental content of natural stone emissions was much higher than that of the engineered stone emissions: 37% in white marble, 33% in white granite and 29% in black granite (Fig. 3 b). The white marble and white granite contained predominantly alkaline metals as Ca and Mg, while the black granite had a more …
