Testing of discrete titanium-based anodes was initiated in September 2006.
The purpose of these tests was to investigate the operating characteristics of three
types of discrete anodes installed in reinforced concrete blocks and to determine the
relationship between acid formation/damage and operating current. The anodes
tested were mixed metal oxide (MMO) catalyzed star-shaped and round
configurations installed in two different types of grouts. Test blocks were operated
indoors and were ponded to prevent over-drying on a cycle similar to the test
procedure used in ASTM Standard Test Method G-109.
