PRESTRESSED CONCRETE
WHAT IS PRESTRESSED CONCRETE
Prestressed concrete is an advanced construction technique that significantly improves the properties of conventional concrete, increasing its strength and durability. Prestressing is the process of applying a compressive force to concrete to compensate for the tensile forces it may experience in service. This is accomplished by means of steel cables that are tensioned before (pre-tensioning) or after (post-tensioning) concreting. Prestressed concrete offers a unique combination of high strength, durability and design flexibility, making it an excellent choice for a wide range of construction applications. Its ability to support large loads and create structures with large clear spans provides significant structural and economic benefits.
USE OF PRESTRESSED CONCRETE
BRIDGE STRUCTURES:
It allows for larger free spans between supports, reducing the number of pillars required and providing a cleaner, more economical design.
TALL BUILDINGS
Used in slabs, beams and pillars, offering high resistance and reducing the total weight of the structure.
INDUSTRIAL WORKS
Applied to industrial floors, tanks, reservoirs and silos, where large free spans and high load capacity are required.
STADIUMS AND ARENA
It facilitates the construction of long, curved structures such as bleachers and roofs.
VIADUCTS AND TUNNELS
Used in segments that require high strength and stability.
MARITIME INFRASTRUCTURE
Piers, wharves and other structures subject to aggressive environments and heavy loads.
TYPES OF PRESTRESSING
Pre-tensioning: The steel cables are tensioned before concreting. Widely used in prefabricated elements, such as beams and slabs.
Post-Traction: Steel cables are tensioned after concreting. Used in in-situ constructions such as building and bridge slabs.
