Ancient Chinese towers were usually built with what materials, and how many years can they resist falling down?

Early Chinese towers were built with wood, but also with bricks, both materials being used simultaneously. Brick could be used to build towers up to 80 meters high.

Because of the simplicity of the early Chinese building materials, has continued for more than 7,000 years, the building materials have not been developed, and has always used the so-called "Qin brick Han tile", that is, soil, wood, brick, stone, very little metal. It is with these materials to build countless various styles of magnificent buildings, which is sufficient to illustrate the diligence and wisdom of the Chinese people.

Ancient Chinese architecture is the use of soil, wood, brick, stone four basic materials, but in the northwest region is built with soil tower, and still retains a lot of soil tower. With wood tower, very difficult, and need a lot of wood, so the wooden tower is not a lot. Moreover, wooden pagodas are not easy to protect, they are not fireproof and are easy to collapse after corrosion. A large number of towers are built with bricks, brick towers are strong and durable, China has preserved the most brick towers, if not encountered an earthquake, brick towers will not collapse. Preserve the brick tower, Songshan Songyue Temple Tower in Dengfeng County, Henan Province, the most intact, so far more than 1,500 years (Figure 4-14). But the early tower, first, the foundation is not very careful, some foundations with rammer solid, above that is built more than ten layers of brick towers, the foundation is intact and will not sink; In addition, China built a tower with brick masonry is bound to use mortar, no cement in the early years, there is no viscous adhesive material, it is to grind the brick masonry, or mortar of the tower, because of the early mortar to the clay-based, mixed with a small amount of lime, there are many brick towers are made with pure The yellow mud mortar masonry. The tower of the Tang Dynasty bricklaying all with yellow mud mortar, not a bit of white ash, until the Song Dynasty brick tower masonry with yellow clay mixed with lime mortar, so that the tower is exceptionally strong, and will not collapse on its own.

There are a small number of towers built with iron called iron tower, which is extremely small. There is also a tower with glazed veneer, but also basically for the brick tower, in the brick tower on the glazed, in order to prevent rain, increase the beauty of the tower, make the tower gorgeous, but the number of glazed towers is even less, but only one in a thousand.

For the tower built with this material, how many years of life. If there is no earthquake, the brick tower can be resistant to 2000 years, but there should be planned maintenance and maintenance, followed by the tower should not be too many people, otherwise there is damage to the tower, once found local rupture, we must be ready to carry out repairs.
