Abstract
A method for preventing corrosion of a reinforced concrete structure having a reinforcing steel embedded therein, which comprises coating an aggregate-containing primer on the surface of the reinforced concrete structure, to form a primer layer having a rough surface, metal-spraying a metal having an ionization tendency larger than iron on the primer layer to form a metal spray coating layer, and connecting the metal spray coating layer and the reinforcing steel by an electrically conductive material.

A method for preventing corrosion of a reinforced concrete structure having a reinforcing steel embedded therein, which comprises coating an aggregate-containing primer on the surface of the reinforced concrete structure, to form a primer layer having a rough surface, metal-spraying a metal having an ionization tendency larger than iron on the primer layer to form a metal spray coating layer, and connecting the metal spray coating layer and the reinforcing steel by an electrically conductive material.
A method for preventing corrosion of a reinforced concrete structure having a reinforcing steel embedded therein, which comprises coating an aggregate-containing primer on the surface of the reinforced concrete structure, to form a primer layer having a rough surface, metal-spraying aluminum or an aluminum alloy on the primer layer to form a metal spray coating secondary electrode layer, forming a primary electrode layer of zinc, a zinc alloy or a zinc-aluminum pseudo alloy at least partially on the secondary electrode layer, and connecting the secondary electrode layer and the reinforcing steel by an electrically conductive material.
