The sliding mandrel for cement-concrete enclosures has a structural core part forming a core (1) of ribbed steel with a minimum tensile strength of 250 MPa. The core (1) is provided with a composite surface (2) consisting of a glass fibers (4) filler having a diameter in the range of 8 µ to 12 µ and a minimum length of 3 mm, which are uniformly distributed in the polyamide (3) binder. Glass fibers (4) in the composite surface (2) are represented in an amount of 15 to 50% by weight, wherein the ratio between the diameter of the structural core (1) part and the thickness of the composite surface (2) is in the range of 18-45%.
