Abstract
A method and apparatus are for fabricating a concrete product in a slip-form casting process, in which method concrete mix is fed into a slip-form mold of a defined cross section moving progressively in the casting process so as to obtain a concrete product of a desired shape. The method includes an interruptible guidance control of the prestressing tendons so as to allow the tendon guides to travel past supplementary parts such as reinforcing steels connected to the prestressing tendons.
