Natural stone is mined from natural rock, and processed into blocks or plates of the general term.The two most basic types of stone used in the building decoration industry are natural stone and artificial stone.Natural stone materials such as marble, granite, limestone and so on.The natural stone materials used for building decoration mainly include granite and marble.Natural stone is one of the oldest civil engineering materials.Natural stone material has high compressive strength, good wear resistance and durability, after processing, the surface is rich in decoration, wide distribution of resources, rich reserves, easy to use local materials, low production costs, is the ancient and modern civil engineering to build city walls, Bridges, houses.Main materials for road and water conservancy projects.It is one of the main decorative materials in modern civil engineering.
Natural stone material can be divided into 3 kinds roughly.Igneous rocks are formed by the cooling and consolidation of molten or partially molten material such as magma from the mantle or crust. Granite is a type of igneous rock.Sedimentary rocks are rocks formed by the weathering products of other rocks and some volcanic eruptions in a place not too deep on the earth's surface, which are transported, deposited and diagenesis by water or glaciers. Sandstones and sandstones fall into this category.Metamorphic rocks are metamorphic rocks that are formed naturally by mixing high temperature and pressure with minerals. Marble, SLATE, quartzite and jade are metamorphic rocks.
Granite is a very hard igneous rock with high density, resistance to scratches and corrosion.It's great for floors and countertops.There are hundreds of varieties of granite.
Marble refers to sedimentary or metamorphic carbonate rocks, including marble, dolomite, limestone, sandstone, shale and SLATE, etc., which are derivatives of limestone. Marble is a kind of metamorphic rock that can be polished and polished.Marble is soft and easy to scratch or corroded by acid.There are countless kinds of marble all over the world.
Limestone is a type of sedimentary rock that is composed of calcite and sediments, forming various colors.
Sandstone is also a type of sedimentary stone, which is mainly composed of loose quartz sand particles, rough texture, sandstone also has many varieties to choose from.
SLATE is a kind of metamorphic rock, the original rock is argillaceous, silty or neutral tuff, which can be shelled into thin sections along the direction of lamination.The color of SLATE varies with the impurities it contains.Black or gray with carbon;The meeting hydrochloric acid that contains calcium can blister, because this is general, name with its color classification, if meeting green SLATE, black SLATE, calcium SLATE.Artificial stones are made from unnatural mixtures, such as resins, cement, glass beads, aluminum powder, etc., and gravel binders.Artificial stone (also called "artificial marble").Artificial stone came out in the United States 30 years ago, China's earliest use of artificial stone products as decorative materials is the mid-1990s some coastal developed cities, a few years after the widespread popularity.
Culture stone is mined in nature stone ore, which SLATE, sandstone, quartz stone, after processing, become a decorative building materials.Cultural stone material is hard, bright color, rich texture, different styles, with compression, wear resistance, fire resistance, cold resistance, corrosion resistance, low water absorption rate.
Marble refers to sedimentary or metamorphic carbonate rocks, including marble, dolomite, limestone, sandstone, shale and SLATE.For example, the famous white marble in China is the dolomite produced in fangshan of Beijing, the marble in yunnan is the marble produced in Dali county, and the famous dandong green is serpentine silicified karnite.Same, as all kinds of magmatic rock that stone material quarries, be like an shanxian, diabase, green feldspar, gneiss to wait for to call granite.If the white granite of Beijing baihu jian is granite, jinan green is gabbro, and the black granite of Qingdao is diabase.
