ABSTRACT
The test piece, as shown in Fig. 8, simulates reinforced concrete, with the underside exposed to salt-induced damage. The test piece was installed on a steel frame located one(1)-meter above ground outdoors. On its underside, cathodic protection testing was performed using a zinc sheet. The zinc sheet was placed on the surface of the concrete through the backfill. In Japan, the reason for testing the underside is based on the fact that sea water spray and/or splashed sea-salt particles often adhere to the underside of structures, such as piers and road bridges, causing salt-induced damage.
