SELF-COMPACTING CONCRETE WITH ULTRAHIGH PROPERTIES, METHOD OF ITS PRODUCTION AND USE Russian patent published in 2009 - IPC C04B28/04 C04B111/20 C04B111/62 

FIELD: construction.

SUBSTANCE: invention pertains to self-compacting concrete of light shade with ultrahigh properties containing: cement, mixture of various types of sands of calcinated bauxites of various grain-size composition: fine sand with average grading less than 1 mm and coarse sand with average grading less 10 mm, if necessary white carbon, wherein size of 90% of particles is less than 1 mcm with the average diametre of 0.5 mcm; white carbon is introduced in the amount of not more than 15 wt shares per 100 wt shares of cement, anti-foam compound, super - plasticising admix, if necessary fibers and water, additionally super - small particles of calcium carbonate with specific area equal to or more than 10 m²/g, with form factor equal to or more than 0.3, preferably equal to or more than 0.4, whereat grain-size distribution of various types of cement and sand, super - small particles of calcium carbonate and of white carbon forms three and five various grain-size fractions, ratio between the average diametre of particles of one fracture and average diametre of particles of the other fracture makes 10.

EFFECT: production of concrete of light shade with high mechanical properties.
