METHOD OF ELECTRICAL CURING OF CONCRETE IN WINTER Russian patent published in 2005 - IPC

FIELD: construction; method of an electrical curing in winter .

SUBSTANCE: the invention presents a method of an electrical curing in winter conditions and is dealt with construction, namely, with the methods of the winter concreting with use of electrical preheating. The technical result is improved water impermeability and strength of the outer layer of concrete. The method provides for a heating with the help of the electro-heated mats and placement on the surface of the fresh-formed concrete mixture of a protective covering. At that before application of the protective covering a row of notches are made on the surface of the fresh-formed concrete mixture in a random order with following pressing in it a mixture made out of a dried fine-grained material. After it in the capacity of the covering they apply on that outer layer a double vulcanized along the perimeter plastic film the top part of which is solid, and the bottom part is perforated with the area of perforation of 30-70%.

EFFECT: the invention ensures improved water impermeability and increased strength of the outer layer of the concrete.
