The polarization performance of two types of commercial galvanic point anodes for
protection of rebar around patch repairs is evaluated. Experiments include measurement of the
polarization history of the anode under galvanostatic load simulating various aging regimes.
Additionally, the anodes were evaluated in reinforced concrete slabs with residual chloride
contamination and in field installations. Preliminary results indicate that only modest
performance may be achieved with typical expected anode placement spacing in commonly
encountered applications.
