FIELD: construction.
SUBSTANCE: high-strength light fibrous concrete produced from a mix containing cement, microsilica with average particle size of 0.01-1 mcm, quarry waste, product of grinding of quartz sand with specific surface of 700-800 m2/kg, quartz sand of fraction of 0.16-0.63 mm, hyperplasticiser on polycarboxylate base, basalt and/or polypropylene fibre and water, additionally contains a microsphere filler at the following ratio of components, wt %: portland cement - 34.5-52.7, microsilica - 7.0-13.65, specified quarry waste - 1.5-11.9, specified quartz sand - 5.1-31.3, microspheres - 4.3-19.2, specified hyperplasticiser - 0.3-0.48, specified fibre - 0.3-1.5, water - balance.
EFFECT: increased bending and compression strength, improved deformative properties.
