FIELD : corrosion protection.SUBSTANCE : invention provides homogenous corrosion-inhibiting composition, which contains 20-30% water-soluble phosphate, 5-20% starch, and balancing amount of zeolite and/or schungite, said water-soluble phosphate being selected from alkali or alkali-earth metal phosphates, orthophosphates, and dihydrogenorthophosphates, in particular dipotassium phosphate. Composition may further contain sodium or potassium silicofluoride. Composition is of especial importance for use as corrosion inhibitor for solid antiicing agents based on inexpensive and accessible chlorides, particularly magnesium chloride.EFFECT : increased efficiency and stability of protective properties and duration of effect, especially on building and road-building materials.1 tbl
