摘要： Concrete mass is extruded onto a bed into a space between the bed and a mould, and the mass is compacted. After the compaction, the surface layer of the product is again caused to enter into a plastic state by means of vibration and recesses discontinuous in the casting direction are pressed into the surface layer thus plasticized. The apparatus comprises a mould (2, 3) formed of a cover portion and side walls, as well as means (1, 2, 3) for feeding and compacting the concrete mass. At least one mould wall has a pressing means (5) provided with a vibrator. The pressing means (5) provided with a vibrator is placed after the compaction step (3). The pressing means (5) is provided with discontinuous ridges.
