FIELD: chemistry.
SUBSTANCE: invention relates to armature corrosion inhibitor based on water solution of fluorine-containing salt. Additionally introduced are derivatives of lignosulphonic acids with the following component ratio (wt %): fluorine-containing salt - 0.3-1; derivatives of lignosulphonic acids - 30-33; water - the remaining part.
EFFECT: said inhibitor of armature corrosion makes provide more stable passive state of armature in concrete with lower working dosage due to reduction of cement stone permeability and electrochemical effect.
