The invention relates to a method and an apparatus for producing concrete blocks, in which concrete mortar ( 14 ) is moved across a mould ( 7 ) by means of a filling carriage ( 4 ) and the mould ( 7 ) is filled with concrete mortar ( 14 ) from the filling carriage ( 4 ), whereupon the filling carriage ( 4 ) is returned and the concrete mortar ( 14 ) located in the mould ( 7 ) is compacted first of all by means of a plunger ( 13 ), movable from above in the direction of the mould ( 7 ), and then by vibration, the plunger ( 13 ) being moved via two synchronized motors ( 15 ) located one behind the other in the direction of travel of the filling carriage ( 4 ) and the torques exerted by said motors ( 15 ) being measured, the filling operation of the mould ( 7 ) being corrected in accordance with the deviation of actual values, derived from the difference in the measured torques, from predetermined desired values.
