METHOD FOR PREPARING MIXTURE FOR COMPOSITE CELL CONCRETE Russian patent published in 2015 - IPC C04B38/02 C04B38/10 B82B3/00 

FIELD: chemistry.

SUBSTANCE: method for preparing a mixture for composite cell concrete involves supplying the ingredients of the composition into a mixer and agitating them to prepare a homogenous mixture, introducing a dry powder mixture into the prepared composition and agitating together; a zeolite additive prepared by pre-agitation of one- or multi-layer nanotubes in water by an atomiser in the sprayed form and agitated with zeolite in a cyclic mixture, is introduced into the composition; the prepared dry powder mixture consisting of dry foaming agent, PAP-2 aluminium powder and PAP-1 aluminium powder is also added; the ingredients of the dry mixture is supplied into a common mixture in the following proportions, kg: cement 600, fly ash of CHP plants 400, microsilica MKU 50, superplasticising agent C-3 9, sodium oleate 3, sodium gluconate 15, adiment CT-2 2, Lastonox biocidal additive 2, fibre 1.5, polymer additive 5, above dry powder mixture 20, above zeolite additive containing one- or multi-layer nanotubes 50; the common composition resulted from agitation is exposed to impact mechanic activation on UDA plants.

EFFECT: preparing the homogenous dry mixture, reducing the bulk density, increasing strength and frost resistance of non-autoclaved cell concrete prepared from the declared dry mixture.
