Abstract (en)

Walling blocks of concrete or similar material with variable dimensions and/or shape are made in open mould boxes (1) by placing at least one blanking piece (12) within the mould box (1). The blanking piece (12) is made of elastic, compressible material and is in the shape of a rectangular prism with a height (H) in the unloaded state corresponding to the height of the box (1). The remaining space (16) is filled with concrete (15) which is then compressed by a plunger (14) covering the cross-section of the box so that the blanking piece (12) is compressed at the same time. The side walls (3,4,5,6) of the box are then removed, the plunger (14) is raised, the blanking piece (12) is released and the walling block (20) allowed to harden.
