METHOD OF PREPARING GAS CONCRETE MIX Russian patent published in 2001 - IPC

FIELD: building materials industry, more particularly manufacture of products from cellular concrete are used for making wall blocks and panels and heat-insulating devices. SUBSTANCE: turbulent-type mixer is successively filled with silicic filler, aluminium power and binder, and components are stirred for 3-10 minutes at rpm of mixer working member of 250-550 rpm, and paraffin film is thus removed from surface of aluminium particles, silicic filler includes gold-slag mixture with particle size of less than 5 mm. The resulting mixture consisting of silicic filler, aluminium power and binder is stirred with water after preparing mixture of some time later, or at least not later than 3 months from preparation thereof. EFFECT: high-quality gas concrete products and simplified process due to combination of preparation of gas-forming agent and stirring of mixture components, lower energy capacity of the method. 4 cl, 2 tbl
