BINDING AGENT Russian patent published in 2007 - IPC C04B12/04 C04B7/28 

FIELD: construction materials industry; chemical reactor and the method for production of hydrogen.

SUBSTANCE: the invention is pertaining to the construction materials industry and may be used in the field of construction for manufacture of the products and the constructions out of the heat-resistant concretes. The technical result of the invention is the increased heat resistance of the binding agent. The binding agent includes the fly-ash of the second field produced from the incineration of the Kansk-Achinsk brown coal at the Heat-and-power station-7 of Bratsk city of Irkutsk region, and the carbon-containing water glass manufactured out of the large-tonnage wastes of production of the crystalline silicon of Bratsk city aluminum works - the micro-silica containing 12-15 mass % of carbon impurities - graphite C and carborundum SiC, with the silica modulus n=1 and the density р=1.36-1.33 g/cm³ at the following ratio of the components (in mass %): the indicated carbon-containing water glass - 37.5-47.4, the indicated fly ash - 52.6-62.5.

EFFECT: the invention ensures the increased heat resistance of the binding agent.
