Applications of Limestones
Limestone is an organic sedimentary rock, which is basically a result of skeletal fragments of marine creatures which is majorly enriched with minerals calcite and aragonite, that are actually different forms of calcium carbonate in crystal form. Applications of limestone are several and discussed here. It primarily comprises calcium carbonate (CaCO3), which is present in the form of mineral calcite. It is generally created in warm, clear and shallow marine waters. Limestone is also a chemical sedimentary rock which is created via precipitation processes of calcium carbonate acquired from lake water or ocean water. Some applications of limestone include in segments of paper, paint, rubber & plastics, wherein it is used as a filler.
Since ages, limestone has been the first choice for construction and continues to be one till date. Its light weight makes it highly suitable for shorter buildings and also provides toughness to the structure. The properties of the product makes it versatile for any form of structure worldwide. Modular construction or structures make use of concretes and in order to provide these concretes strong binding limestone happens to be the chief and main component which is mixed with cement to do the needful.
In concrete, limestone is used as aggregate. A kiln is used for fire it up along with crushed shale, which results in the production of cement. Few limestone varieties are highly preferred for concrete since they have less pore spaces and are strong, dense rocks. In line with this, they have good resistance against abrasion and freeze-thaw. Here, the applications of limestone is preferred because it is simple to mine and causes less wear on the mining equipment and transportation vehicles.
