Galvashield anodes contain an activator that causes the zinc core to corrode. Does this also cause reinforcing steel corrosion?

Galvashield anodes are alkali-activated with a pH of 14 or greater. This activator is corrosive to zinc but not to steel, therefore there is no concentration of corrosive elements left concrete after the zinc is consumed that could accelerate corrosion of the reinforcing steel. Some anodes utilize high concentrations of halide activators (i.e. chloride or bromide) which are corrosion to both zinc and steel and will remain in the concrete even after the anode is consumed.
