Abstract

The present invention relates generally to a device and a method for casting concrete elements or slabs. The invention concerns especially a method for casting concrete elements (8) comprising the steps of: preparing a base (1) for casting, placing a mould (5) on the base (1); pouring fresh concrete (7) into the mould (5), which in curing forms the concrete element (8); and allowing the fresh concrete (7) to cure until at least a predetermined minimum shape permanence of the concrete element (8) has been achieved. The invention is characterized by the steps of, when the concrete element (8) has achieved said shape permanence, raising it from the base (1) to temporarily disengage its underside therefrom to essentially eliminate the forming of any shear stresses as the concrete element (8) shrinks, thereby preventing the occurrence of any shrinkage cracks; and, after the concrete element (8) has essentially finished shrinking, lowering it onto the base (1) to be used.
