ABSTRACT:
A method and an apparatus for casting concrete elements from a concrete mix by slipforming molding which involves extruding the concrete mix onto a bed, generating pressure into the concrete mix by a first set of extruder members and by compacting the concrete by moving at least one of the movable mold walls in a direction approximately parallel to its plane. The concrete mix is tamped into a more compacted form by protrusions formed onto at least one of the movable mold walls and projecting into the mix. The method and the apparatus achieves a high degree of compaction in the concrete mix by an uncomplicated method and apparatus without generating a loud noise.
