Abstract
Noncorroding reinforcing steel, and steel reinforced concrete, which has an adherent bond with hydrated concrete formed by a thermally sprayed hydraulically reactive layer of a material such as blast furnace slag on the steel surface.
Claims9
A steel reinforcement for concrete which has the capability of forming an adherent bond with a cement matrix, comprising a steel reinforcement substrate, and a thermally sprayed, adherent, cementitiously reactive layer adherently applied to said substrate.
A method for manufacturing corrosion-resistant concrete having an interface between the bulk cement matrix and the steel reinforcement which is at least as strong as the cement paste of the bulk cement, comprising the steps of providing a steel reinforcement, thermally applying a cementitious surface coating on the surface of said steel reinforcement, placing the coated steel reinforcement in an aqueous concrete slurry, and curing the concrete slurry in contact with the coating to provide a steel-reinforced concrete.
