Method for inibicao from corrosion of rehabilitation and / or protection of the ACO reforcado soaked in a structure of cement hardened through the application of compositions that inhibit corrosion applied surface

摘要

The present invention provides methods and compositions for the reduction of the corrosion rate of already corroding steel reinforcements embedded in a hardened concrete structure as well as for the protective corrosion inhibition of uncorroded steel reinforcements embedded in a hardened concrete structure exposed to aggressive environments.;The inventive new compositions employed for the novel method are essentially based on one or more amino- and/or hydroxyalkylamino compound(s), which are partially or completely neutralized with one or more inorganic acid(s) and/or derivatives thereof and/ or aliphatic carboxylic- and/or aromatic carboxylic acid(s), one or more surfactant(s) and optionally, one or more water-based or water-thinnable water repellent agent(s) selected from the group of organosilicones.
