THERMO-INSULATING MASS Russian patent published in 2013 - IPC C04B28/26 C04B111/20 

FIELD: chemistry.

SUBSTANCE: invention relates to building materials and can be applied for producing articles, intended for thermo-insulation of thermal furnace units and energy equipment with temperature of exploitation to 1150°C. Thermo-insulating mass contains Cambrian clay, fireproof clay, form-waste - waste from steel-casting production based on quartz sand, dolomite and crock, milled together to residue on sieve 0.08 not more than 1%, liquid glass with density 1.4-1.5 g/cm³, riddling of building wastes from dismounting of buildings with module of coarseness M_co=2.7, on 80% consisting of broken heavy-weight concrete on granite macadam, with the following component ratio, wt %: liquid glass 28.0-30.0, said riddling 50.0-52.0, Cambrian clay 7.5-8.5, fireproof clay 3.5-4.5, claimed form-waste 3.5-4.5, dolomite - 3.0-3.3, crock 1.0-1.2.

EFFECT: increased strength.
