Abstract:
The method of retarding the rate of corrosion of metallic reinforcements in concrete structures which comprises the steps of:(a) applying a substantially continuous coating of a concrete sealer formulation to the surfaces of a concrete structure wherein the concrete sealer formulation comprises a working solution of a solvent mixture together with:(i) an air-drying film forming sealant component selected from the group consisting of silicates, silane modified siloxanes;(ii) a corrosion inhibitor selected from the group consisting of amine salts, amino alcohols, alkali salts of glucoheptonates, and Ca(NO.sub.2).sub.2 ; and(iii) the film forming sealant component is present in said working solution in an amount ranging from between 10% and 25% by weight, the corrosion inhibitor is present in said working solution in an amount ranging from 0.5% to 5% by weight, the balance being film-forming component compatible solvent.
