FIELD: construction.
SUBSTANCE: disk-shaped working element of a concrete finishing machine includes a drive shaft that can transfer a torque moment to a smoothing disk, with that, in cavities of the smoothing disk there located are magnetrons creating microwave radiation, the electric power to which is supplied by means of sliding contacts through a rheostat, by means of which it is possible to control a microwave radiation gradient.
EFFECT: obtaining high quality of treatment of a surface of concrete items; obtaining a high-strength surface layer.
