Materials used in buildings collectively referred to as building materials. Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramic, glass, engineering plastics, composite materials, etc .; decorative materials including various coatings, paints, coatings, veneers, colored tiles, with special effects Glass, etc .; special materials for water, moisture, corrosion, fire, flame retardant, noise, heat insulation, insulation, sealing and so on.
Stone Building Material refers to the main use of construction masonry or decoration of natural stone. Natural stone for construction is selected, cut or sawn into a specified or specified shape and size, and the surface or surfaces of the Stone Building Material can be machine polished or completely non-surface modified.
Stone Building Material can be divided into three categories:
First, stone (divided into clog stone peace stone);
Second, the material stone (divided into wool stone, coarse stone, semi-fine stone, fine stone);
Third, the decorative stone.
Due to the use of natural finishes decorative stone parts are different, so the choice of stone types are also different. For outdoor building decoration, to be subjected to long-term wind and rain sun, granite because it does not contain carbonate, water absorption, anti-weathering ability, the best selection of various types of granite stone; Facing the decoration of the floor surface of the hall, requiring its physical and chemical properties and stability, high mechanical strength, should be the first choice of granite stone; for the dado and home bedroom floor decoration, less mechanical strength, with a beautiful pattern of marble.
Natural stone refers to the natural rock from the mining, and processed into bulk or plate-like material in general. The two most basic types of stone used in the construction and finishing industry are natural stone and artificial stone. Natural stone such as marble, granite, limestone and so on. Natural stone used in building decoration mainly has two kinds of granite and marble. Natural stone is one of the oldest civil engineering materials. Natural stone with high compressive strength, good wear resistance and durability, the appearance of the beautiful and rich after the processing of decorative, resource-wide distribution, rich reserves, easy to local materials, low production costs, etc., is the ancient and modern Civil engineering in the construction of urban walls, bridges, houses. Road and water conservancy project main material. It is one of the major decorative materials of modern civil engineering.
Natural stone can be broadly divided into three categories. Igneous rocks are formed by the melting or partial melting of the mantle or crustal rocks, such as magma, by cooling and consolidation. Granite is a type of igneous rock. Sedimentary rocks, which are not too deep in the earth's surface, combine weathering products of other rocks with volcanoes Eruptive matter, rocks, and sandstones formed by the transport, sedimentation and diagenesis of streams or glaciers belong to this category; metamorphic rocks are another type of stone that is naturally metamorphosed by a stone under the action of heat and pressure and minerals, marble, slate, quartzite, jade belong to the metamorphic rock.
Granite is a very hard igneous rock that is highly densified, scratch-resistant and corrosion-resistant. It is ideal for floors and kitchen countertops. There are hundreds of varieties of granite. Granite plate is mainly used for large-scale public buildings or decorative grade demanding indoor and outdoor decoration projects. Granite is not easy to weathering, the appearance of color can be maintained for more than a century, so rough and thin panels commonly used in outdoor floors, walls, cylinders, levator feet, pedestals, steps; mirror plate is mainly used for indoor and outdoor ground walls Surface, cylinder, countertops, steps, etc., especially suitable for large public building hall ground.
Marble refers to sedimentary or metamorphic carbonate rocks, marble, dolomite, limestone, sandstone, shale and slate, is a derivative of limestone, marble is a metamorphic rock can be polished . Marbles are soft and easily scratched or corroded by acids. There are countless marble types all over the world. Natural marble plates are commonly used decorative materials decorative materials. Generally used in hotels, exhibition halls, shopping malls, libraries, airports, railway stations, office buildings, residential projects such as indoor walls, cylinders, service desks, railing, elevator door and other parts.
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 grains. The texture is rough, and there are many varieties of sandstone to choose from.
Slate is a metamorphic rock, the original rock to muddy, silty or neutral tuff, along the board direction can be stripped into thin slices. The color of the slate varies with the impurities it contains. Iron is red or yellow; the carbonaceous is black or gray; the calcium containing case of hydrochloric acid bubbles. Therefore, it is usually classified by its color, Green slate, black slate, calcareous slate and more.
Artificial stone is made with a mixture of non-natural, such as resin, cement, glass beads, aluminum powder, etc. plus gravel binder. Artificial stone (also known as "artificial marble"). Artificial stone came out in the United States 30 years ago. The earliest application of man-made stone products in China was the coastal developed cities of the mid-1990s, which became widespread in a few years. Artificial stone is a synthetic decorative material. In accordance with the different binder, can be divided into organic artificial stone and inorganic artificial stone two categories. According to their different production process, but also can be divided into polyester artificial marble, synthetic artificial marble, silicate artificial marble, sintered artificial marble four types. Artificial veneer stone for indoor and outdoor walls, floors, cylinders, countertops and so on.
Cultural stone is mined in the natural stone mining, which slate, sandstone, quartz stone, after processing, as a decorative building materials. Cultural stone hard, bright color, rich texture, different styles, with pressure, wear resistance, fire resistance, cold, corrosion resistance, low water absorption and so on.
