The difference between granite and marble in everyday life we ??often hear when people say from decorative stone is usually referred to as granite or marble, granite someone said to marble, it was also said to be granite marble, Some even put granite and marble and granite and marble on the petrology confused. In fact, granite and marble are the generic name of goods, and rock types on the petrology of a certain relationship, but there are big differences. Granite refers magmatic rocks with a decorative function, and polished polished and some acidic metamorphic rocks, magmatic petrology, including the granite, syenite, diorite, gabbro and other rock types, Granite granite stone which is applied oldest, most widely used, the largest amount of rocks, granite and therefore it hence the name. Metamorphic rocks, including granite gneiss. Chemical composition of granite is mainly silicates silicon-oxygen tetrahedron backbone structure and, therefore tensile, compressive, shear resistance, low water absorption, while sesame ash dry hanging, the composition of mineral hardness greater so wearable. Because of these characteristics of granite, and the variety, and therefore suitable for decorative exterior walls, floors, stairs, the production of large-scale sculpture and stone products. Marble refers to a decorative function, and polished, polished carbonate rocks, and some contain small amounts of carbonate minerals in silicate rocks, including limestone, marble and so on. While bright colors and beautiful marble, color variety, but because ingredients are smooth sesame gray carbonate smaller hardness. So no acid, no alkali, no corrosion, no wear, not suitable for decorative wall and floor, and is mainly used for the production of decorative interior walls and sculptures, craft products. Dali rich because of this kind of stone, and a long history, hence the name of reason within the stone structure constructed of stone: natural stone there are micro-cracks and hair, forever will absorb airborne fine dust and dirt, as a result of capillary hole effect slowly seep inside the stone, while greatly reducing the performance and life of decorative stone, sesame gray brick smaller pores, capillary action and surface adsorption stronger. Relatively complex chemical composition: Stone some components easily with the environment play a role in sesame gray, or variation of the stone to produce erosion phenomenon. Stone generally contain different levels of iron content by tidal erosion produces yellow rust. Stone higher iron content, the more likely to produce rust. In addition, most of the main component of natural marble carbonate, calcium carbonate and magnesium carbonate, as well as small amounts of alkali oxides. Calcium and magnesium carbonates are relatively stable compounds, in a wet environment, easy and acidic oxides of carbon dioxide in the air, sulfur dioxide, sulfur trioxide, nitrogen dioxide, such as chemical reactions occur, while changing the physical structure of the interior of the marble . Similar chemical damage will occur in the other stone, light stone surface will lose luster, even color Fading, there scar; severe decrease in hardness makes natural stone surface weathering.
