HEAT-RESISTANT SUPERHIGHQUALITY CONCRETE, THE METHOD OF ITS PRODUCTION AND THE BONDING ARRAY FOR THIS CONCRETE Russian patent published in 2006 - IPC C04B28/02 C04B16/06 C04B14/06 C04B14/20 C04B14/46 C04B14/48 C04B18/14 C04B111/28 

FIELD: construction materials industry; production of fibrous concrete.

SUBSTANCE: the invention is pertaining to the field of construction materials industry, in particular, to production of the fibrous concrete. The technical result of the invention is production of the superhighqualitative concrete characterized by the high refractory strength, the controlled rheological properties and the good mechanical properties. The invention characterizes the application of the organic fibers having a fusion point less than 300°C, the medial length exceeding 1 mm and the diameter of no more than 200 micron in the superhighqualitative concrete for improvement its refractory properties. At that the content of the organic fibers is such, that their size makes from 0.1 up to 3 % of the size of the concrete after is hardening, and the concrete in 28 days possesses the compression strength of no less than 120 MPa, the bending strength of no less than 20 MPa and the flow index in the not hardened state is no less than 150 mm. At that these values concern to the concrete being at 20°C, which consists out of the especially hardened cementing array, in which the metallic fibers are distributed. The invention also describes the heat-resistant superhighquality concrete containing metallic reinforcing fibers and the organic fibers ensuring the desirable properties, as well as the method of production of this concrete and the cementing array for the concrete.

EFFECT: the invention ensures production of the superhighqualitative concrete characterized by its high refractory strength, controlled rheological properties and the good mechanical properties.
