FIBRE-CONCRETE MIXTURE Russian patent published in 2011 - IPC C04B28/04 C04B111/20 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of concrete mixtures for making monolithic and precast concrete structures used in construction. The fibre-concrete mixture, which contains portland cement, basalt fibre, plasticiser, sand and water, contains plasticiser in form of S-3 superplasticiser or Melflux 265 IF hyperplasticiser, sand in form of fractionated quartz sand with the following distribution of fractions, %: Fr. 1.25-0.63 60, Fr. 0.63-0.315 20, Fr. 0.315-0.14 20, and also microsilica, with the following ratio of components in wt %: portland cement 25-30, microsilica 3-4, said plasticiser 0.3-0.9, basalt fibre 1.5-2.0, fractionated quartz sand 55-60, water - the rest.

EFFECT: high flexural, tensile, tensile splitting and compression strength, as well as high frost resistance.
