Inhibidor de la corrosión para hormigón armado
It has been found that a composition based on alkylalkoxysilanes or alkylalkoxysiloxanes gives a clear decrease in corrosion current as measured in concrete reinforcement when applied to the reinforcement, even when the concrete has been previously damaged by chlorine penetration. A composition for protection of concrete steel reinforcement against corrosion containing as component A at least one organosilane or organosiloxane of formula (I). R-SiR<1>x(O)yR<2>z (I) R = optionally branched 3-20C alkyl; R<1> = optionally branched 1-4C alkyl; R<2> = optionally branched 1-4C alkoxy or OH; x = 0, 1 or 2; y = 0, 0-1 or 5; z = 0, 1, 2 and/or 3. Independent claims are included for: (1) a process for decreasing the corrosion of concrete steel reinforcement by application of the composition to the steel surface, e.g. by spraying, brushing, rolling or wiping, in amount exceeding 50, preferably 200 g/m<2> of concrete surface; and (2) concrete treated as described above.
