FIELD: building materials production. SUBSTANCE: device to produce concrete blocks has self-propelled gantry. There are drive bins with band-type feeder for moulding mixture, concrete form for moulding, vibration table for the concrete form, and a device for smoothing out, movable matrix block being installed into concrete form, for example, by an elevator. Matrix block is made in the form of closed power hard band with, for example, elastic partitions forming profile apertures are fixed as cantilevers along its internal perimeter. Directed vibrators to facilitate withdrawal of matrix block from the concrete form are installed along perimeter of the power band. Smoothing device can have drive sealing roller with baffles.
