ABSTRACT:
A method is provided for fabricating a concrete slab in a substantially horizontal slip casting process method, concrete mix is fed into a mold through a delimited cross section moving progressively in the casting process so as to form a concrete product of a desired shape. Onto the surface of the casting bed (1) is placed a core (3, 9, 10, 11) capable of delimiting the cross section of the concrete product (5, 5′) so as to provide an opening or a provision for an opening in the bottom surface of the slab. A core is provided for obtaining an opening or a provision for an opening. The structure and/or material of the core is/are such that the core is capable of yielding in vertical direction. A core may also be a multipart core, the outer part of which becomes detached from the inner part of the core in conjunction with lifting off the concrete slab from the casting bed.
