Repar Steel
The anticorrosive efficacy of Repar Steel is determined by the high alkalinity and by the superpozzolanic reaction of the components of the anhydrous system, as well as by the presence, in the liquid component (B), of migratory and interfacial corrosion inhibitors, capable of carrying out cathodic and anodic protection, based on organic compounds capable of making ferrous ions unavailable for feeding electrochemical corrosion processes. The polymeric components of the solution also determine further increases in the anticorrosive efficacy, especially against aggressive attacks deriving from chlorides and sulphates, and increase the adhesion between the treated bar and the concrete (adherence test according to EN 15184 in compliance with the UNI EN technical standard 1504 "Products and systems for the protection and repair of concrete structures - Part 7: Corrosion protection of reinforcements").
Fields of application
Passivating protective anti-corrosive treatment for reinforcing rods in restoration works in reinforced concrete.
Preparation of supports
Carefully remove non-adhering rust, present on the metal surfaces of the exposed reinforcement rods by blasting or deep brushing , until the following condition is reached: "almost white metal" (metal colour as if it has just come out of extrusion).
Mode of use
The mixing of the two components may be implemented by an external mixer or by using a site bucket. Pour the blue solution (component B) into the bucket, while adding the powder gradually and during mixing (component A), mixing until the mixture is completely lump-free; apply by brush on the prepared reinforcing surfaces, for a consumption of about 100 g per metre of oxidized reinforcement to be passivated.
