FIELD: building materials.
SUBSTANCE: invention relates to the building materials industry and can be used in the construction of buildings in civil, industrial construction and in the construction of structures for special purposes. Lightweight self-compacting structural concrete is obtained from a mixture containing, wt.%: mechanically activated Portland cement 15-25, polyfunctional modifier on a polycarboxylate base 1-2.5, rheologically active stone flour 10-25, water-retaining additive 0.003-0.02, micro- and nanosilica 1.5-7, glass ceramic foam granules 30-50, water - the rest.
EFFECT: obtaining lightweight self-compacting structural concrete of high strength, high frost resistance, low cost and low thermal conductivity.
