FIELD: construction.
SUBSTANCE: method for manufacture of products from concrete includes moulding by means of open molds filling with polystyrene mix, extraction of freshly moulded previously hardened products from moulds, transportation to the area of hardening and maintenance under natural conditions to final hardening of concrete. At that after extraction from mold prior to transportation to area of hardening previously hardened items are cooled down for 5÷10 minutes at the temperature of -10÷-25°C till surfaces layer freezes down to depth of 2÷5 mm.
EFFECT: improved reliability and strength of products and acceleration of manufacturing process.
