SOIL REINFORCEMENT METHOD AND COMPOSITION FOR SOIL REINFORCEMENT Russian patent published in 2020 - IPC E02D3/12 E01C3/04 E01C21/00 

FIELD: construction.

SUBSTANCE: group of inventions relates to industrial and civil construction, namely to reinforcement of soil with cementation with introduction of a polymer composition for reinforcement, consisting of organic and inorganic substances, into a cement-sand solution. Composition for soil strengthening is an aqueous solution, with the following ratio of components, wt. %: acrylic dispersion 5–30, glycerine 2–5, petroleum bitumen 0.01–0.5, sodium polyphosphate 0.01–0.5, calcium chloride 10–40, boric acid 0.01–1, sodium silicate 2–10, water 100 %. Method of soil reinforcement includes saturation of soil with 10 % aqueous solution of sodium silicate with addition of said composition for strengthening soil in amount of 2–8 l per 1 m³ of solution, cementation of soil with cement mortar with addition of said composition for soil reinforcement in amount of 0.1–2 wt. % per 1 m³ of soil.

EFFECT: technical result is high processing properties of fixer, high stability of used composition, as well as strength of soil treated with fixer.
