When people talk about natural stone, most people think of granite and marble, and few think of limestone. However, limestone is a material that has many applications in natural stone buildings. In this paper, we introduce what this material is, some of its characteristics, and how it is used.
What is limestone?
The surface of natural limestone is composed of natural limestone. But what is limestone? The general answer can be simply: "limestone is a sedimentary rock found in the aquatic environment."
Limestone is a common carbonate sedimentary rock. It is mainly composed of calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). When these minerals precipitate from water containing dissolved calcium, they form limestone. This can be achieved through biological and abiotic processes, although biological processes may be more important in the past 540 million years.
The composition of natural stone will affect the use and appearance of stone, and even the care and maintenance required. In addition, the processing method of materials is affected by their constituent materials. Therefore, materials composed of the same minerals will have similar characteristics and are considered relevant.
Hardness of limestone
Compared with other natural stones, calcareous stones are relatively soft. Because of this, the hardness of limestone on the Mohs scale of mineral hardness is 4 or 5.
How is limestone used?
Limestone is widely used and cannot be listed one by one. However, what we need to do is to give you an expression and let you understand the idea. Limestone powder, size stone, slate and ceramic tiles are used in a variety of practical products in a variety of ways, including:
Paper, glass, paint, cement, plastic, concrete, medicine, cosmetics, toothpaste, lava, wallboard, floor tile, size stone, soil conditioner, roof particles, coal mine safety dust, building facade, animal feed filler and sculpture materials
It is easy to see from the above that limestone is a kind of material with a wide range of uses and various forms. Its use is the product of its main component minerals.
