Pre tensioning :

  1. In this method the concrete is prestressed with tendons before it is placing in position.
  2. This method is developed due to bonding between the concrete and steel tendons .
  3. Pre tensioning is preferred when the structural element is small and easy to transported.
  4. In this method similar prestressed members are prepared .

Post - tensioning

  1. In this method prestressing is done after the concrete attains it's strength
  2. This method is developed due to bearing
  3. Post tensioning is preferred when the structural element is heavy
  4. In this method products are changed according to structure .
