Progress Report on Inhibiting the Corrosion of Steel In a Reinforced Concrete Bridge

Experimental techniques used to inhibit the corrosion of steel in a reinforced concrete bridge are described. Control methods used include application of cathodic protection, addition of capillary water to the concrete to produce oxygen starvation and use of paints to produce moisture equalization within the concrete. Role of absorbed moisture and sea salts in promoting corrosion is discussed briefly. Because several tests still remain to be made and evaluated, data are presented as a progress report, not as conclusions for design criteria. 5.2.1
