Abstract (en)
[origin: EP0454098A2] A process for making concrete elements (10) of a substantially pot-shaped form is proposed, in which the concrete elements (10) are formed in the fabrication position, which is the inverse of the service position, in a mould (12), which has a mould core (14) and a radially outer mould mantle (16), arranged at a distance from the mould core (14). During the course of the process, an insert element (34) is placed on the upper end (14b) of the mould core (14), a mould cavity (24), formed between mould core (14) and mould mantle (16), is filled with concrete until the insert element (34) is completely covered to a desired layer thickness, the filled-in concrete is compacted, the concrete element (10) is stripped and allowed to set, the concrete element (10) remaining in the fabrication position at least until after setting and the projection of the outer circumference (34a) of the insert element (34) running on a plane running perpendicularly to the axis of the concrete element (10) between the projection of the outer circumference (14c) of the mould core (14) and the projection of the inner circumference (16a) of the mould mantle (16). <IMAGE>
