RAW MIXTURE FOR MANUFACTURE OF THE WALL ASH-CERAMIC ARTICLES Russian patent published in 2008 - IPC C04B35/16 

FIELD: construction materials industry; other industries; production of the raw mixture used for manufacture of the wall ash-ceramic articles.

SUBSTANCE: the invention presents the raw mixture, which is pertaining to the compositions for manufacture of the wall ash-ceramic articles. The raw mixture used for manufacture of the wall ash-ceramic articles contains the micro-silica and ash. At that in the capacity of the ash use the ash produced at burning in the furnaces with the fluidized bed of the sand of the dehydrated deposits of the sewage disposal plants of the timber industry complex enterprises, which are characterized by the specific area of the surface - 115m²/kg in the grain composition of the ash the mass share of the particles of less than 0.14 mm makes 72 % containing in its chemical composition SiO₂ making 48.83 %, at the following ratio of the components: the micro-silicon - 30-40 %, the ash produced after burning of the dehydrated deposits of the sewage disposal plants of the industrial timber complex enterprises - 60-70 %. The technical result of the invention is the increase of the strength, the frost resistance and the factor of the design quality at reduction of the temperature of the ash-ceramic articles calcination.

EFFECT: the invention ensures the increased strength, the frost resistance and the factor of the design quality of the ash-ceramic articles at reduction of the temperature of their calcination.
