What are the Advantages of Prestressed Concrete?
Prestressed concrete is a type of concrete created using steel wires or bars that create tension within it. These steel elements are used to increase the strength of the concrete and prevent cracking or deformation.
The fundamental principle of prestressed concrete is that steel elements placed inside the concrete, when tensioned after the concrete hardens, create prestressing. This prestressing increases the tensile strength of the concrete, reducing or preventing cracks or deformations when additional loads are applied to the structure.
The advantages of prestressed concrete are as follows:
Some areas where prestressed concrete is used;
Bridges
Prestressed concrete is used in the main structural elements of bridges, allowing for longer spans and fewer supporting columns.
Skyscrapers
In high-rise buildings, prestressed concrete is used in columns that bear the weight of the building and in slabs on the ground floor.
Dams
Prestressed concrete is used in dams, which are structures resistant to water, to increase their strength.
Roads
In areas with high traffic such as highways and airports, the use of roads made with prestressed concrete is more durable and long-lasting.
Tunnels
In tunnels, prestressed concrete is used to enhance the stability and strength of the structure.
Storage Tanks
Structures such as chemical storage tanks and oil tanks are constructed using prestressed concrete, resulting in a more durable and secure structure.
