What is a concrete bridge?
Concrete bridge is a structure made of concrete and built to cover a certain distance. Concrete bridges usually allow vehicles or people to cross physical obstacles such as lakes, rivers, valleys or roads. Concrete is one of the most common types of materials used in the modern bridge structure.
Construction of concrete bridge can have many advantages. In general, concrete is a highly universal substance because it can withstand a wide range of climates. It can be mixed in a way that gives it the ability to withstand extreme temperature fluctuations and corrosive chemicals. As a result, the concrete bridge works well in most regions of the world. Concrete is also a flexible material that allows the engineer to be creative in planning aesthetic attributes of the concrete bridge construction project. In fact, some types of Concrete can take up to 100 years. For this reason, concrete bridges are often lower maintenance than other types of bridges with less total maintenance costs. The cost of the initial design isAlso often lower with concrete than other types of materials.
The prestressed concrete bridge is a type of concrete bridge that has gained popularity since the late 40 years. This is particularly useful in extending the ability of the bridge span. In principle, the prestressed concrete is designed to counteract the limits associated with the formation of stress in the concrete. The overtaken concrete bridges usually contain reinforcing sticks made of fabrics such as steel cables or bars that are mounted in concrete. These columns help to emphasize that the bridge would realize.
Concrete is one of the most widespread materials in the current arc bridge design. The specific arch bridge consists of a structure with a curved arch, which serves as the main support mechanism. In addition, the arc bridge usually contains two supports that are located at each end of the curved arch. Modern bridges for concrete oThe wands are usually designed from reinforced concrete, which contains steel reinforced sticks.
A specialized concrete type, known as high -performance concrete, can be used in the construction of a concrete bridge. The high powerful concrete is designed to exceed the performance of conventional concrete. Usually, the material ratio with water cement has about 0.40 or less, although this number may vary depending on the type of bridge. The position for the bridge also affects the proportions of high -performance concrete mixtures, as temperature and other factors require a change in water cement ratio.
