FIELD: technological processes.
SUBSTANCE: present invention relates to metallurgy. Exothermic mixture includes the following, wt %: aluminium powder 16.0-27.0, liquid glass 6.0-7.0, ACEG hardener 0.6-0.7, sludge of nitre baths of thermal production of 2.5-7.5, sludge of hardening tanks 13.0-22.0, refractory filler making the rest. Use of wastes in the mixture composition increases its fluidity, ruled out the forming operation from the production of articles from the mixture.
EFFECT: provided is higher strength, heat-insulating properties, gas permeability and survivability of articles from the mixture.
