1, bluestone is widely used in living rooms, dining tables, cabinets and counters after being cut into plates by masons from deep mountains.
2. Bluestone is the raw material of lime. In addition to lime, bluestone is also mined by stone factories as stones and large sand. Stone is a component of cement, and big sand becomes a necessity for building houses.
Bluestone is also used to crush many hard stones, such as river pebbles, pebbles, granite, limestone, marble and bluestone. Bluestone is widely used in highways, high-speed railways, rural roads, building sand and other fields, and is an ideal material for the construction industry.
Extended data:
Limestone is mainly formed in shallow sea environment. Limestone can be divided into granular limestone (deposited by running water) according to its genesis; Bioskeleton limestone and chemical and biochemical limestone. According to the structural structure, it can be subdivided into bamboo limestone, limestone and massive limestone. The main chemical composition of limestone is soluble calcium carbonate, so many stone forests and caves have been formed in limestone areas, which is called karst topography.
Limestone generally contains some dolomite and clay minerals. When the content of clay minerals reaches 25%~50%, it is called argillaceous rock. When the content of dolomite reaches 25%~50%, it is called dolomite limestone. Limestone is widely distributed, with uniform lithology and easy to be mined and processed. It is a widely used building material.
The main component of limestone is calcium carbonate, which is soluble in water containing carbon dioxide. Generally speaking, a liter of water containing carbon dioxide can dissolve about 50 mg of calcium carbonate.
