CONCRETE MIXTURE Russian patent published in 2009 - IPC C04B28/02 C04B14/38 B82B1/00 B82B3/00 C04B111/20 

FIELD: construction industry.

SUBSTANCE: invention refers to concrete mixture compounds. Concrete mixture including cement, filler, water, and basalt fibre with diametrer of 8-10 mcm and 100-500 mcm long and modified with the matter chosen from the group that includes multi-layer polyhedral carbon fulleroid-type nanostructures having interlayer distance of 0.34-0.36 nm, average particle size of 60-200 nm and bulk density of 0.6-0.8 g/cm³, and multi-layer carbon nanotubes having interlayer distance of 0.34-0.36 nm; that matter is taken in quantity of 0.0001-0.005 part by mass for one part of basalt fibre by mass; at that mixture contains filler that is chosen from the group involving gravel mixed with sand and gravel mixed with aluminosilicate microspheres, and is used as filler; and in addition, concrete mixture contains plasticising agent-sodium polynaphthalene methylene sulfonate at the following component ratio (wt %): cement 24-48, filler 30-60, modified basalt fibre 2-6, plasticising agent 0.9-1.1, and water is the rest.

EFFECT: producing concrete with improved strength properties and water resistance.
