why is plastic used in limestone

Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiologi

These are (i) raw limestone which is also the natural form of limestone, (ii) calcined limestone or quicklime, or simply lime, and (iii) as hydrated lime. When limestone is used as a fluxing material then it is used as either raw limestone or as calcined limestone.

Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches,
