PRESTRESSED CONCRETE BEAMS PRODUCTION PROCESS
Prestressed beams have an important key role in making the prefabricated halls and other constructions (for example the bridges) that require high bearing power. Production is accomplished in the factory where industrial production is used. Prestressing is considered as a case when additional loading is added to an element by force. Production of these beams is usually complex process. Despite that fact, prestressed beams have numerous advantages as compared to traditional reinforced concrete and this is why they’re widely used in every part of the world. Referring to the methods of prestressing, production process uses pretensioning and post-tensioning. Referring on how the connection between prestressed wires and concrete was done there are bonded and unbonded post-tensioned concrete. No matter what kind of prestressing was used, the objective of the production process is to produce beams which meet requirements to be effective and economical. In practice, batch and serial production are often used in order to achieve transportability, assemblage and accuracy of production.
