FIELD: chemistry.
SUBSTANCE: invention relates to the repair-insulating grouting compositions based on magnesia binders. The proposed repair-insulating grouting composition contains, wt %: magnesium oxide - 36.76-34.91, heptahydrate magnesium sulphate - 0.37-0.33, sodium hexametaphosphate - 3.7-0.1, nitrilotrimethylphosphonic acid - 1.7-0.1, magnesium chloride - 33.09-31.42, zinc carbonate and/or manganese sulfate - 3.68-3.49, water - the rest.
EFFECT: increasing the strength of the insulating material for bending, stability when exposed to the water environment, while there is no loss in the strength characteristics of the composition under conditions of flooding.
