    Prestressed concrete - Wikipedia

    • Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces. Its wide range of application is reflected in its incorporation int… 展开

    Pre-tensioned concrete

    Pre-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned prior to the concrete being cast. The concrete bonds to the tendons as it cures, following which the end-anchoring of the tendons i… 展开

  1. Prestressed concrete is a type of concrete that has initial compressive stresses applied to it during production. This added step is taken to strengthen the concrete against the external forces that will be applied to it eventually during use.

    What is prestressed concrete used for?
    Prestressed concrete is therefore used in high-scale structures where heavy loads are placed on it from different angles. Can be used for longer spans. Since the concrete is both reinforced and prestressed, foundations can be longer in length without the risk of breakage.

    What materials make up prestressed concrete?
    Steel. The other material that makes up prestressed concrete is some sort of high tensile strength steel reinforcement. This could be in the form of tendons, bars, wire strands, or cables. When prestressed during the manufacturing process, these steel tendons are what give the prestressed concrete its tensile strength.

    What is prestressing & how does it work?
    As mentioned before, prestressing is the application of an initial load on the concrete structure, so that the structure is able to counteract or withstand the stresses coming due to the service loads. The concept can be clearly understood by the example of a barrel.

    Is prestressing a real thing?
    In fact, the practice of prestressing things is very older in our day-to-day life. Imagine a barrel made of wooden staves and metal bands. Tung-Yen Lin, a civil engineering professor at the University of California, explained it in the introductory chapter of his book “ Design of Prestressed Concrete Structures ".
