Although the application of the calcium carbonate in the buildings’ construction is more appropriate for humid regions, its resistance against acidic materials is low; the acidic rainfall is a significant problem in areas where calcium carbonate is widely used. The dissolved acid in acidic rainfall can damage the buildings, thus, soft limestone powder can be used to neutralize the effects of acidic rainfalls.
Specialized in the production of (calcium carbonate), which is used in many industries such as: Paints, rubber, plastics and coatings industry, paper industry, building materials industry and industry Iron and steel, pharmaceutical industries, food, animal feed, fertilizers and industry Glass, optics, solar energy panels and many other industries.
ساختار اندام دام دارای ذخایری از منیزیم است. که بخش عمده ای از آن در است.خوان های مهره ها و دنده نگهداری می شود. و هنگامی که در دام ها کمبود منیزیم اتفاق می افتد،به منظور جبران آن از ذخیره منیزیم است.خوانهایشان است.فاده میکنند. که این حالت در دام های جوان اتفاق می افتد در حالی که دام های بالغ به علت کمبود منیزیم در اثر بروز Tetany تلف می شوند.
Pure limestone is often found in white and whitish colors. Due to the presence of impurities such as clay, organisms remains, iron oxide and other components, most of the limestone are found in different colors, especially if they are weathered. Based on their formation process, limestone could be seen in crystalline, clastic, granular or massive forms in nature. The presence of calcite, quartz, dolomite or barite crystals may create some small cavities in rocks. The Folk and Dunham classifications are used to scrutinize the limestone in detail.
The calcium carbonate is soluble in some compounds such as acids, therefore many erosional structures such as calcareous caves, potholes, and deep valleys may be created. Some erosional features are known as karst. Although calcium carbonate is less resistant than igneous rocks, its resistance is higher than other sedimentary rocks. Usually, the Calcium carbonate is present in hills and sink hole structures, and often could be seen with other sedimentary rocks such as clay in different regions.
