Marble by sedimentary and sedimentary metamorphic rocks, the main component is the content of calcium carbonate, about 50%-75%, a weak alkali. Some Marble Slab contains a certain amount of silica, some do not contain silica. Fine particles (refers to calcium carbonate), the surface stripe distribution with irregular, hardness is generally low. The composition of the structure characteristics of the marble is the has the following properties:
(1) good adornment performance, marble contains no radiation and colour and lustre is gorgeous, color is rich, is widely used in indoor wall, ground adornment. With excellent processing properties: saw, cutting, polishing, drilling, sculpture, etc.
(2) the wear-resisting performance of the marble is good, not easy ageing, its service life generally in 50-80 years or so.
(3) in industry, Marble Tile is widely been applied. Such as: used for raw materials, purification, etc.
(4) marble has not electric magnetic field, a stable characteristics.
From A business perspective, all natural form, can the calcareous rocks are polishing marble, not the marble called would apply to all of the building, so the marble occasions should be divided into A, B, C and D four categories. This kind of classification is especially suitable for relatively fragile type C and D kind of marble, they before installation or the installation process need special treatment.
