Types Of Stone

Natural stone refers to the general term of materials extracted from natural rock mass and processed into block or plate materials. The two most basic types of stone used in the building decoration industry are natural stone and artificial stone. Natural stone such as marble, granite, limestone, etc. The natural stone used for building decoration mainly includes granite and marble. Natural stone is one of the oldest civil engineering materials. Natural stone has high compressive strength, good wear resistance and durability, beautiful and decorative surface after processing, wide distribution of resources, rich reserves, convenient local materials, low production costs and other advantages. It is the main material for building city walls, bridges, houses, roads and water conservancy projects in ancient and modern civil engineering. It is one of the main decorative materials of modern civil engineering.
Natural stone can be roughly divided into three categories. Igneous rock is formed by the melting or partial melting of rocks in the mantle or crust, such as the cooling and consolidation of magma. Granite is one kind of igneous rock; Sedimentary rocks are rocks and sandstones formed by the weathering products of other rocks and some volcanic eruptions in places not too deep on the earth's surface through the transportation, deposition and diagenesis of water flow or glaciers; Metamorphic rock is another kind of rock naturally metamorphosed from one stone under the mixed action of high temperature and pressure and minerals. Marble, slate, quartzite and jade are all metamorphic rocks.
Granite is a very hard igneous rock with high density, scratch resistance and corrosion resistance. It is very suitable for floors and kitchen countertops. There are hundreds of varieties of granite.
Marble refers to sedimentary or metamorphic carbonate rocks, including marble, dolomite, limestone, sandstone, shale and slate, which are derivatives of limestone. Marble is a metamorphic rock that can be polished. Marble is soft and easy to scratch or be corroded by acid substances. There are countless kinds of marble all over the world, and new wood-grained jade blanks are recommended.
Limestone is a kind of sedimentary rock, which is composed of calcite and sediment and forms various colors.
Sandstone is also a kind of sedimentary stone, which is mainly composed of loose quartz sand particles with coarse texture. There are many kinds of sandstone to choose from.
Slate is a kind of metamorphic rock. The original rock is argillaceous, silty or neutral tuff, which can be peeled into thin slices along the direction of foliation. The color of slate varies with the impurities it contains, and the iron-bearing slate is red or yellow; The carbonaceous ones are black or gray; Calcium-containing rocks will blister in the presence of hydrochloric acid, so they are generally classified according to their color, such as green slate, black slate, calcareous slate, etc. Artificial stone is made of non-natural mixture, such as resin, cement, glass beads, aluminite powder, etc., with crushed stone adhesive. Artificial stone (also known as "artificial marble"). Artificial stone came out in the United States 30 years ago. The earliest use of artificial stone products as decorative materials in China was in some coastal developed cities in the mid-1990s, and it was widely popular a few years later.
Cultural stone is a kind of natural stone mineral, in which slate, sandstone and quartz stone are processed into a decorative building material. Cultural stone materials are hard, bright in color, rich in texture and different in style, and have the characteristics of compression resistance, wear resistance, fire resistance, cold resistance, corrosion resistance and low water absorption.
The so-called marble refers to sedimentary or metamorphic carbonate rocks, including marble, dolomite, limestone, sandstone, shale and slate. For example, China's famous white marble is the dolomite produced in Fangshan, Beijing, Yunnan marble is the marble produced in Dali County, and the famous Dandong green is serpentinized skarn. Similarly, all kinds of magmatic rocks, such as andesite, diabase, chlorite and gneiss, which are mined as stones, are called granite. For example, the white granite in Beijing Baihujian is granite, Jinan Qingqing is gabbro, and the black granite in Qingdao is diabase.
Artificial stone is a kind of artificial decorative material. According to the different binders used, it can be divided into organic artificial stone and inorganic artificial stone. According to the different production process, it can be divided into four types: polyester artificial marble, composite artificial marble, silicate artificial marble and sintered artificial marble.
