5.5: Classification of Sedimentary Rocks
Crystalline Limestone. Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ( CaCO3) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 ). About 10% of sedimentary rocks are limestones.

Quarry limestone dust as fine aggregate for concrete
In this process waste fine aggregates (dust waste) are generated. The disposal of this type of waste is a further cost in the extraction process, but also a possible cause of environmental pollution (e.g. leaching into water reserves, atmospheric pollution as a result of small particles causing respiratory diseases or deposited on plants ...
Effect of Limestone Particle Size and Potassium …
In the present study, the fine limestone-fed broilers tended to exhibit decreased WB scores (P = 0.08) at 35 days of age. During the grower period, the BWG in fine limestone-fed broilers trended lower (2,194 vs. 2,208 g). These results implied that a smaller BW may have been associated with decreased WB myopathies.
