The advantages of using self-compacting concrete in the technology of precast reinforced constructions that are manufactured on stands with a travelling shuttering were considered. Considering the significant heat losses on the heating of products in this technology, concretes have been studied that harden at low temperatures. It was shown that self-compacting concretes with consumption of 330-450 kg / m3 gaining strength in compression of 20-35 MPa for 16-20 hours at low temperature heating.
