COMPOSITION FOR INJECTION SOLUTION Russian patent published in 2017 - IPC E02D3/12 C04B28/02 C04B14/26 C04B111/20 

FIELD: construction.

SUBSTANCE: invention relates to construction, and specifically to soils injection fixing compositions, mainly loess, in existing and newly constructed buildings and structures foundation. Injection solution composition contains binder and filler, wherein binding component is OTDV “Mikrodur”, and used filler is carbonate rock with chemical composition, wt%: CaO – 55.58; CO₂ – 24.56; SiO₂ – 9.42; Al₂O₃ – 2.90; MgO – 2.08; Fe₂O₃ – 1.05; SO₃ – 0.53; CuO – wt%: OTDV “Mikrodur” 20–50, carbonate rock 50–80.

EFFECT: technical result is reduction of costs and increased efficiency by providing high strength and water resistance of soil concrete mass, fixed by solution based on composition with maximum reduction of expensive imported product, OTDV (super fine binder) “Mikrodur”, with filler from local raw material, carbonate rock, which is brought to fine state.
