FIELD: manufacture of building materials, concrete and reinforced concrete articles in particular. SUBSTANCE: articles are acted on by electromagnetic field at one of stages. Pulse field is created by electrical video pulse packets following continuously; duration of pulse packet is equal to 2•10-4-2•10-3 s at pulse period-to-pulse duration ratio ranging from 10 to 100 and specific power of 0.01-0.1 W/cu m. EFFECT: increased rate of gaining strength of article. 5 cl, 2 dwg
