In this research two kinds of experiments were performed from a basic point of view to prevent reinforcing bars embedded in concrete being corroded by covering the surface of concrete with using Metallized Zinc and Zinc Aluminum Coating. One is experiments on corrosive substance separating effect and another is experiments on sacrificial cathodic protection. The results of tests show that the corrosive substance on reinforcing bars can be expected to be avoided by spraying suitable metals over the surface of concrete, and that sacrificial cathodic protection can be expected to be protected for corrosion by using Metallized Coating on condition of maintained the water content of the concrete, anode/cathod area ratio under 5 and adjustment of the consumption of it.
