A method for rehabilitative and/or protective corrosion-inhibition of reinforcing steel embedded in a hardened concrete structure by means of surface-applied corrosion-inhibiting compositions |
摘要 |
<p>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.</p> |
