Abstract
The formwork for a concrete structural member includes a recoverable formwork part. This recoverable part has an axially elongated sheath which closely encloses a tendon over a relatively long portion of the length of the sheath. A cup-shaped part formed integrally with the sheath is arranged to form at least a portion of a recess in the concrete member. When assembled on the formwork, one end of the sheath is arranged to be located within the concrete when it is poured and the other end is located on the exterior of the formwork. The cup-shaped part is located intermediate the ends of the sheath and just inside the formwork. A member is engageable with the sheath for attaching it to the formwork.
