Advantages and disadvantages of natural marble

Natural marble is a metamorphic rock formed by the high temperature and high pressure of the original rock in the earth’s crust. It belongs to medium hard stone and is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is calcium carbonate, accounting for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide, and silicon dioxide.

a. The natural marble tile texture is compact but not very hard, easy to process, sculpt and smooth, polished and so on. The marble is polished and smooth, the texture is natural and smooth, and it has a high degree of decoration. Marble has a low water absorption rate and high durability and can be used for 40-100 years.

b. Natural marble has a fine texture and solid texture. After polishing, it is as clean as a mirror. The texture is more stretchy and beautiful than granite. High compressive strength (after granite), depending on the rock formation, up to 300 MPa, low water absorption, wear resistance and deformation.

a. Since marble generally contains impurities, and calcium carbonate is exposed to carbon dioxide, carbides, and moisture in the atmosphere, it is also easy to weather and dissolve, and the surface quickly loses its luster. Therefore, a small number of relatively stable and durable varieties such as white marble and Ai Yeqing can be used outdoors, and other varieties are not suitable for outdoor use, and are generally only used for interior decorative surfaces. The main varieties are: cloud gray marble, colored marble and so on.

b. Radioactivity: The natural marble is radioactive. The qualified natural marble has strict control over the radioactivity of the stone and will not cause harm to the human body.
