ABSTRACT:
The invention relates to an apparatus and method for manufacturing concrete structural elements. In order to manufacture the elements, setting of the concrete takes place in a casing (1), while the concrete is compressed with an axial pressure of at least 50 MPa and the casing is surrounded with a hoop (2,3) so as to create transverse planes of pressure.
