FIELD: chemistry.
SUBSTANCE: invention relates to building materials and can be used in making cellular non-autoclave foamed concrete, as well as for making pieces and monoliths. The dry mixture for making cellular foamed fibre reinforced concrete contains the following in wt %: portland cement 20-75, mineral filler 7-75, microsilica 0-6, superplasticiser based on sodium salts of products of condensation of naphthalene sulphonic acid and formaldehyde 0.1-2.5, modifying additive consisting of a combination of aluminosilicate microspheres and one or more multilayered carbon nanotubes in ratio of 1:10 0.1 - 5, foaming agent 0.002-0.45, polypropylene fibre up to 1.5 kg per 1 m3 of the dry mixture.
EFFECT: simple manufacturing technology, improved physical and mechanical characteristics: frost resistance, resistance to different types of emissions, including radiation.
