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.

Protecting the environment and green areas is one of the most important issues that Al-Moasron Group pays attention to Its concern for preserving the environmental balance and the continuation of green life on the land of our beloved Kingdom is our goal It is to reduce the negative impact on the environment and preserve it in every good or service that we provide.

The calcium carbonate is a sedimentary rock which is mainly composed of calcite mineral (calcium carbonate: CaCo). The calcium carbonate is often composed of various quantities of silica mineral in the form of chert or flint, as well as various amounts of clay, silt, and sand, as intercalations, nodules or interbedded layers. The main source of calcite in limestone is usually marine organisms, so that their shells deposit on the ocean floor. As well, the secondary calcite may be deposited by supersaturated meteoric waters (ground waters that cause the deposition in caves), and consequently cave deposited layers such as stalagmite and stalactite are formed.

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.
