What kind of rock is suitable for building materials?

Because of the legendary Luban in China! Chinese woodworking technology arose earlier than the West in ancient times, and has been inherited and carried forward so far, which is the reason for the good foundation!

If we also live on a barren ridge, then the construction of many stone villages is logical, but if we have a large number of forest resources, it will naturally not waste time on the stone, so in the primitive period, the production efficiency of the ancestors' labor force is low, then the transportation capacity is also very affected, it must be the principle of proximity, It is only used according to the amount of material that is most around you, so there are not many other cultural explanations for this.

The degree of civilization is different, and the technical level of stone building is low, similar to primitive means. The use of wood in ancient Chinese architecture reflects the progress of technology and artistic aesthetics. Rock (stone) and sand are important aggregates for the production of concrete and are indispensable.

Sedimentary rocks have bedding structure, and the influence of layering and bedding on the engineering properties of sedimentary rocks is mainly anisotropy. Therefore, the occurrence of sedimentary rocks and their interrelationship with the location of engineering buildings have a great influence on the stability of buildings. At the same time, due to the different material compositions of the rocks, they also have different engineering geological characteristics.

Not all rocks can be used in the construction industry, some rocks can but more rocks can not be used in the construction industry, here we have to distinguish them, otherwise it will cause the problem of building instability. It depends on performance and strength. For example, as a concrete crushed stone, igneous rock generally requires a strength greater than 80MPa, and aqueous rock requires a strength of 60MPa.

For example, rocks such as mica are flake cleavage and are not suitable for building materials, etc.

The main chemical component of stones in building materials is silica, followed by a small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds. There are granite, limestone, quartz, and complex silicates of different compositions. Structurally speaking, there are magmatic rocks, sedimentary rocks, and metamorphic rocks, which are then transported by rivers, and the proportions vary from place to place.

Generally, it is a more natural rock, and then some marble, granite or mineral aggregates will be selected, these materials are generally relatively stable, and the building ** is also more affordable.

Personally, I feel that sedimentary rock is more suitable for building materials, because the building materials made of sedimentary rock are more layered, and the quality is also very good.

Quartz, marble, granite, metamorphic rock, slate, slate, these rocks are very suitable for building materials, and they are all very strong and beautiful.

1.Marble: Marble has a delicate rock surface texture and is often used as a wall or floor.

Since marble is metamorphized from limestone, the main component is calcium carbonate, so it is also a raw material for making cement. Marble is soft and delicate, making it a good stone for sculpture, and many famous statues are made of marble, such as the famous Venus statue. Others, such as wall cladding or ornamentation, are also often made of marble, such as vases, ashtrays, tables and other household items.

2.Granite: Native granite can only be seen in Kinmen, so almost all of Kinmen's old houses are made of granite. The granite used in Taiwan's temples comes from Fujian and is mostly used for dragon pillars, floor tiles, and stone lions in temples.

3.Slate: Because it is easy to crack into thin slabs and is easy to obtain in mountainous areas, the aborigines still use slate as a building material to build slate houses or walls.

4.Conglomerate: Some conglomerates contain pebbles and sand, and they are poorly cemented, which is easy to disperse, for example, this kind of conglomerate is found in the Quaternary Toushan Formation in western Taiwan, in which pebbles and sand are building materials.

5.Limestone: The most common limestone in Taiwan is formed from coral, commonly known as coral reef limestone. In Penghu, coral reef rocks are commonly known as stones, and residents use them as building materials for fences to shelter from the strong northeast monsoon and protect crops.

6.Mudstone: Because its main component is clay, it has been used as a raw material for bricks and pottery since ancient times.

7.Andesite: Due to its hard material, it is also commonly used as dragon pillars for temples, stone carvings on walls, tombstones, floor tiles, etc.

1. Rock is an important building material and industrial raw material, 2 is a raw material for daily necessities and carving crafts, 3 It also contains rich and valuable resources, especially various metal substances used by human beings such as coal, oil, and natural gas, which are contained in the lithosphere of the earth's crust.

There are three main types of rocks – magmatic rocks, sedimentary rocks, and metamorphic rocks. The buildings are mainly granite, marble, etc.

Igneous rocks. Molten material from the Earth's interior, condensed and consolidated into rock under different geological conditions. When lava erupts from a volcanic channel and solidifies on the surface, it is called ejecta rock or volcanic rock. Common volcanic rocks include basalt, andesite, and rhyolite.

When the lava rises before reaching the surface and condenses at a certain depth in the earth's crust, the rocks are called intrusive rocks, which are divided into plutonic rocks and shallow rocks according to different intrusion sites. Granite, gabbro, diorite are typical plutonic rocks. Granite porphyry, gabbro porphyry, and diorite porphyry are common epigenetic rocks.

Sedimentary rocks are layered rocks formed by the transportation, sedimentation and diagenesis of weathered materials, volcanic detritus, organic matter and a small amount of cosmic materials under normal temperature and pressure conditions on the surface. According to the genesis, it can be divided into clastic rocks, claystone rocks and chemical rocks (including biochemical rocks). Common sedimentary rocks include sandstone, tuff sandstone, conglomerate, claystone, shale, limestone, dolomite, siliceous rock, ferroid, phosphatite, etc.

Metamorphic rocks are rocks formed by metamorphism. According to the different types of metamorphism, metamorphic rocks can be divided into five categories: dynamic metamorphic rocks, contact metamorphic rocks, regional metamorphic rocks, mixed rocks and metasomatic metamorphic rocks.

Common metamorphic rocks include mylonite, clastic rock, hornstone, slate, phyllite, schist, gneiss, marble, quartzite, amphibole, schist, dolerite, mixed rock, etc.

The stone generally used in industrial and civil buildings is mainly blue-gray, cryptocrystalline limestone, which is difficult to see obvious crystals with the naked eye, and can also be called limestone.

Limestone is mainly formed in a shallow sea environment. Limestone can be divided into granular limestone according to its genesis (flowing water transport, sedimentary formation); Bioskeleton limestone and chemical, biochemical limestone. According to the structural structure, it can be subdivided into bamboo-leaf limestone, limestone, and massive limestone.

The main chemical component of limestone is caCO3 that is easily dissolved, so stone forests and karst caves are mostly formed in limestone areas, which are called karst terrain.

Limestone is the main raw material for burning lime and cement, and is a flux for ironmaking and steelmaking.

Limestone is widely distributed, the lithology is uniform, easy to mine and process, and it is a very versatile building stone.

Granite is also used on individual construction sites, and granite is generally a porphyry structure with visible crystalline grains. It is quite different from limestone.
