A first starting component of the polymeric cement is present inside said tubular vessel near the first axial end wall. A shaft extends through said aperture of the second axial end wall. A piston element comprises a closed container filled with a second starting component of the polymeric cement. The piston element is selectively lockable to the shaft. The container has a bore and is slidingly engaged upon said shaft. An agitator element is secured to one end of the shaft. Furthermore opening means for providing an opening in the closed container are provided.
