FIELD: chemistry.
SUBSTANCE: invention relates to compositions sued as binder for soil, and can be used in construction and mining. A two-component composition for reinforcing soil by injection contains as an isocyanate component polyphenylene polymethylene polyisocyanate containing 30-31% NCO groups, and as a hydroxyl component a homogenous mixture of alkoxylated alkanetriol with molecular weight of 370-500, ethylene glycol, a urethane-forming catalyst selected from a group comprising dimethylethanolamine and methyldiethanolamine, potassium acetate and a diluent selected from a group comprising chlorinated paraffin wax CP-470 and a mixture thereof with dibutyl phthalate, with content of the isocyanate and hydroxyl components in equal volumes.
EFFECT: invention enables to obtain a composition with low viscosity and no tendency to demixing, having a low reaction temperature and limited foaming.
