Granite and limestone are divided into completely weathered rock, strong weathering rock, medium weathered rock, what is the difference between them?
The quality of granite depends on its composition and structure. Good quality granite, crystal grain is fine and uniform, mica content is little and quartz is more, and do not contain pyrite. Granite is not easy to deteriorate, the appearance of color can be maintained for more than a hundred years, so more used for wall and exterior wall decoration. Due to its high hardness and abrasion resistance, granite is also commonly used in the construction of high - rise buildings. Granite and marble compared to the more hard and acid, and therefore more suitable for home decoration in the outdoor balcony, courtyard, guest house on the ground and windowsill. The marble can be used for the bar, dining table, dining counter table. 1, granite stone: Granite stone is no color stripes, the majority only color spots, there is a pure color. The finer the mineral particles, the stronger the structure is. 2, marble plate: Dali stone mineral composition is simple, easy to process, most of the delicate texture, mirror effect is better. Its shortcoming is that the texture is more soft than granite, and it is easy to be damaged when it is hit by hard heavy objects. As far as possible to choose the best choice of floor tiles, the choice of the table when the stripes of the better effect of decorative cloth. Other selection methods can refer to the selection of granite. The types of stone commonly used today are divided into four categories: sedimentary rock, metamorphic rock, igneous rock and artificial stone.
Natural marble is a metamorphic rock formed by high temperature and high pressure in the crust. It is a hard stone, mainly composed of calcite, limestone, serpentine and dolomite. The main components of calcium carbonate, accounting for more than 50%. Other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. As a result of the marble generally contain impurities, and calcium carbonate in the atmosphere by carbon dioxide, carbide, water vapor, but also easy to weathering and corrosion, and make the surface soon lose luster. So a few of the more stable, durable such as white marble, Ai Yeqing, pure quality, less impurity species can be used outdoors, other varieties should not be used outdoors, generally used only for indoor decorative surface. Can be made of natural marble decorated panels and senior decoration engineering, for public construction projects in hotels, exhibition halls, shopping malls, theaters, libraries, airports and stations etc in the indoor wall, toward the surface, railings, window panels, floor, desk, elevator front finishes, interior decoration materials ideal is advanced. In addition, it can also be used to make marble murals, arts and crafts, daily necessities and so on.
Architectural decoration, decorative stone with marble and granite. Marble is mainly used for indoor, granite is mainly used for outdoor, are senior decorative material. The utility model has the advantages of good decorative effect, durability and high cost, and the utility model is widely used in the projects with high requirements of public building and decoration. But in recent years, with the improvement of living standards, people's aesthetic concept of their own living environment is also constantly updated, marble and granite are more and more in the home decoration. Stone is mainly divided into two categories of man-made and natural, here mainly introduce natural marble and natural granite.
Granite is one of the names of all the stones that you say. The lime, what the wind is different with the color of the rock surface. The general design will not be too detailed, or when it will not arrive will affect the construction period, are generally provided by manufacturers to choose the style and to ensure that the supply and delivery period.
