A respective longitudinally extending resin sheath surrounds each cable between its ends and a plurality of spacers spaced longitudinally along the cables and their sheaths hold same transversely apart with the concrete mass extending between the sheaths. An anticorrosion and antifriction agent inside each sheath surrounds each cable inside the respective sheath between the respective cable ends and a respective anchor braces each cable end against the concrete mass.
